Best FlyingPress Settings: Ideal Setup to Pass Core Web Vitals in 2025

Are you looking for the best FlyingPress settings to improve your site’s Core Web Vitals score on PageSpeed Insights? If you are, keep reading this article.

I will also discuss why I switched from WP Rocket to FlyingPress last year and what my FlyingPress setup entails, which delivers a significant performance boost and improved search engine rankings.

The current setup on this TechNumero blog is:

• GeneratePress + GenerateBlocks Pro — Lightweight WP Theme
• Kinsta — Fastest Managed WordPress Hosting
• FlyingPress — Best WP Caching Plugin
• Perfmatters — Best WP Optimization Plugin
• Cloudflare CDN Free version

🌐 See Plans to start!

A lightweight theme and a fast WordPress hosting are not always good enough to pass Core Web Vitals. To speed up your WordPress website or WooCommerce store, you should have the best WordPress performance optimization plugin and the ideal configuration.

This way, you can optimize the server resources and performance for core web vitals, such as the time to first byte, largest contentful paint, and cumulative layout shift.

If you search for a WordPress optimization plugin, you will find multiple options like WP Rocket, WP Super Cache, W3 Total Cache, etc. These are all good plugins for beginners and let you optimize your site up to a certain level.

However, when you’re serious about your business, you should opt for the best. I highly recommend using FlyingPress for your caching and speed optimization needs, as it checks all the right boxes and offers numerous optimization features.

Why I Decided to Use FlyingPress

Here is why I decided to use FlyingPress instead of WP Rocket:

• Very easy to configure, default settings do 90% of optimization.
• Advanced unused CSS handling with multiple loading options (asynchronously, on user interaction, or remove entirely).
• Local hosting of third-party code, CSS & JS, including Gravatars and fonts.
• Lazy Render HTML Elements can lazy load entire sections like comments, footers, and related posts.
• YouTube placeholder optimization with self-hosted thumbnails.
• Smart image exclusion that automatically excludes above-the-fold images.
• Always-on caching that serves as a fallback even with other caching layers.
• FlyingCDN integration with Cloudflare Enterprise features at affordable pricing.
• Built-in Bloat Removal with extensive options.
• And obviously, better value for money than the competition.

FlyingPress Speed Test Results

I have configured FlyingPress on TechNumero with the exact same configurations I am going to share later in this article, and here is the Google PageSpeed Insights result I have achieved.

Mobile Speed Test:

What I have got is:

• LCP – 2 seconds
• INP – 99 milliseconds
• CLS – 0.09 seconds

Are you wondering how to configure it?

Do not worry. In this FlyingPress tutorial, I will show you the best FlyingPress settings you can use to improve the website’s performance. You can score better on speed testing tools like Google PageSpeed Insights and GTmetrix using the ideal configurations provided below.

First, let’s see what FlyingPress is and who created it.

What is FlyingPress?

FlyingPress is a premium WordPress speed optimization plugin designed to dramatically improve website performance and Core Web Vitals scores with minimal configuration.

Developed by Gijo Varghese, a well-known name in the WordPress performance optimization community, FlyingPress serves as an all-in-one performance solution that combines advanced caching, code optimization, and modern web performance techniques.

Gijo added so many cutting-edge features to the plugin. Some of the most valuable features of FlyingPress are:

• Cache preloading
• Database optimization
• Links preloading
• Image optimization
• Static file minification
• Google Fonts optimization
• CDN integration
• Bloat control

And so on.

Currently, FlyingPress has only a premium version. But all the purchases are protected with their 14-day money-back guarantee. Hence, if you are unhappy with the plugin or the results you get after configuring it, you can easily claim a full refund.

Now you know what FlyingPress is.

Next, let’s see how to configure the performance optimization plugin to get 100/100 on speed tests and score better on Google PageSpeed Insights and GTmetrix.

For specific setups, I will discuss the advanced settings of the FlyingPress plugin in the following section.

Best FlyingPress Settings Explained

Let me share my current setup of the FlyingPress plugin with Perfmatters and the best practices to improve page loading speed and boost overall performance. Will discuss all the FlyingPress optimization features, such as:

• Optimization
• Caching
• CDN
• Database
• Bloat
• Settings

Let’s take a closer look at every FlyingPress cache plugin. The user interface of FlyingPress is optimized for users. Finding the right tools or options from the user interface won’t be challenging.

However, installing and activating the plugin is quite simple. The plugin has a keyless activation technique where you do not need to enter your license key manually.

It is one of the advanced features offered by FlyingPress. For some reason, if the keyless activation is not working, you can manually activate the plugin by entering your custom license key.

1. Dashboard

Here is what the dashboard looks like:

As you can see in the image above, there are no detailed configuration options.

You can see

• The total pages cached
• URLs in queue
• An option to preload the cache
• A button to purge the entire cache and preload it.

The main configuration happens inside the plugin’s settings pages. That’s where you can configure the plugin and tweak your site’s performance.

Let’s see how it is done properly.

Without any further ado, let’s see the main FlyingPress settings.

1. Optimization

The core performance can be found under the optimization tab. From here, we can tweak the

• CSS & JavaScript
• Images, Videos & iFrames
• Fonts
• Rendering

Let’s see what each option has to offer in terms of website speed optimization.

1.1 CSS & JavaScript

Static files, such as CSS and JavaScript, can significantly slow down a website if they aren’t optimized properly. Let’s see how to use FlyingPress for these static file optimizations.

The plugin will also allow you to exclude or include specific files from the optimization. So, if any of these optimizations break your website, exclude that particular file that broke your website from the optimization.

• Minify CSS and JavaScript: Enabled – This is a must-have optimization option. Enabling this will remove every unwanted character and whitespace from the CSS and JS files. Therefore, JS and CSS minification are essential.
• Remove Unused CSS: Enabled – This is another highly recommended option to optimize the CSS code. As the name says, you do not need to keep the “unused CSS”. So, better remove them.
• Delay All JavaScript: Load after interaction – Delaying JavaScript executions is another thing I highly recommend. By optimizing execution time, you can enhance the core web vitals score and improve user experience. Select the ‘Load after interaction’ option here.
• Load Third-Party Scripts on Interaction: Depends – In case you select the load when idle or load deferred option for JS, delaying this option will be visible. Once you have enabled this option, FlyingPress detects and automatically delays third-party JavaScript, such as ads and analytics, until it is interacted with.
• Delay Specific Scripts on Interaction: Depends – If you want to delay specific JavaScript files manually, you can use this option. Enable this and include the necessary JS files to delay. A standard set of JS files you can delay are:

ga( '
ga('
google-analytics.com/analytics.js
analytics.js
gtagv4.js
analytics-minimal.js
/gtm.js
/gtag/js
gtag(
/gtm-
adsbygoogle.js
fbevents.js
fbq(
/busting/facebook-tracking/

• Self-host External CSS and JavaScript: Enable – Calling CSS and JS files from an external server can increase the HTTP requests. Plus, your website’s loading time will also depend on the third-party server. To prevent this, enable this option so you can host those files locally. It is quite useful and improves performance when you locally host third-party scripts integrations like Google Analytics, Google Maps,

You can use Google PageSpeed Insights and GTmetrix to track the improvements in the Total Blocking time, Time to Interactive, First Contentful Paint, and Largest Contentful Paint.

1.2 Images, Videos & iFrames

Images require significant resources to load, which can impact the overall load time. In this section, I will show you how to optimize those media files with FlyingPress.

• Lazy load the images, videos, and iframes: Enabled – This is the main option you need to enable for lazy loading the on-page media elements. Once you have activated this, you can lazy load Images, videos, and YouTube iframes. It’s intelligent lazy loading, also defer loading of background images added via CSS, which improves image delivery. You must enable this image loading optimization.
• Properly Size Images: Enable – This option ensures that images load with the correct dimensions.
• Lightweight YouTube Previews: Enable – Instead of showing the YouTube videos in iframes, you can replace them with a YouTube thumbnail image preview. Highly recommended if you embed too many YouTube videos on your website.
• Self-host Gravatar Images: Enable – Similar to hosting fonts locally, you can also host Gravatar images locally. This way, you can reduce the additional third-party requests. This can help you improve the loading time.

1.3 Fonts

The next configuration I have for you is font settings. You can optimize the Webfont load on the server by using the right FlyingPress settings. Here is the ideal Google fonts tuning option you should use:

• Preload Fonts: Enable – To speed up the font loading, you can preload them. This will ensure the text is visible as soon as the font is preloaded.
• Self-host Google Fonts: Enable – Once you have enabled this option, FlyingPress will self-host Google Fonts. This way, your web server doesn’t need to call the Google font server for the fonts constantly. This will help you with the initial page load and HTTP requests. If you are not using any third-party fonts, keep this option.
• Use System Fonts First: Enable – Once you have enabled this option, the plugin will temporarily use the system fonts to display the text while the custom fonts are being loaded.

1.4 Rendering

To improve the initial page speed, you can lazy render HTML elements. Lazy render elements are one of the most popular and effective practices for website speed optimization.

To do this, enable the rendering option, and that’s it.

You can also exclude specific elements from rendering. To add custom elements, click the exclusions button and list those elements.

Once you are done, save the changes.

To find the class, you need to use the Inspect Element tool. Open up a blog post or page and use the inspect option available in the browser.

There, you can see the class ID.

Now add this class to the plugin’s settings and save the changes.

2. Caching

Next, we have the cache settings. Configure the options like this:

2.1 Basic Caching

Here is how to tweak the basic caching options for maximum performance:

• Preload Links on Hover: Enable – Use this feature to load links more quickly. Once the user hovers over the link, FlyingPress will start preloading those, resulting in quick page loads.
• Separate Mobile Cache & Optimizations: Enable – It is always a good practice to generate a separate cache for mobile devices. This way, the desktop version and mobile version cache won’t be the same, which helps if you dynamically change the elements’ visibility on different devices. Generating a separate cache for mobile can speed up the website on mobile devices.
• Cache for Logged-in Users by Role: Disable – This is not mandatory when you handle a blog. On the other hand, if you are running a membership website, you should enable this feature.
• Auto-Refresh Cache: Depends – If you are handling a new website that publishes articles every hour, you need to set a 2-hour interval. On the other hand, if you are running a regular blog, 24 hours is ideal. So, pick an option based on your publishing frequency.

2.2 Advanced Caching

Advanced Caching will help you remove specific

• pages
• query parameter
• cookies

from caching.

This option differs for individual websites and WooCommerce stores.

Let’s take a closer look at each option.

2.2.1 Exclude Pages from Cache

This is an interesting feature. For example, let’s say that you have created a custom checkout page on your WooCommerce store.

The permalink looks like this:

https://example.com/new-checkout

Excluding this page from caching would be the wise choice. So, all you need to do is add the new-checkout element in the exclude option.

From now on, the newly created checkout page will be excluded from the caching.

2.2.2 Separate Cache for Query Parameters

Using this section, you can exclude pages from caching for specific query parameters. As we did earlier, open the settings, enter the query parameter you need to exclude from caching, and save the settings.

2.2.3 Bypass Cache for Cookies

Similar to query parameters, you can also bypass specific cookies from caching. Using the bypass cache from cookies option, you can achieve this.

Enter the cookies and save the settings.

3. CDN

To optimize the file delivery, you could use a CDN. Here are the CDN settings available with FlyingPress.

FlyingPress has its own CDN called FlyingCDN, which is built on top of the premium Cloudflare CDN network and integrates Cloudflare Enterprise features at affordable pricing.

I highly recommend, you sign up for FlyingCDN instead of using other CDN services. I have explained it in detail in a section below.

You are also covered if you are using your existing CDN providers, like BunnyCDN, you can enter the CDN URL and mention which file types should be delivered through the CDN.

BunnyCDN is a good option if you are looking for a performance-optimized and affordable option. Or, you can use Cloudflare Regular or Cloudflare Enterprise with FlyingPress. Since most low-traffic websites only need the free version of Cloudflare, opt for Cloudflare Enterprise if you run a high-traffic website.

My tests showed that FlyingPress with Cloudflare Enterprise would improve the largest contentful paint score by 40%.

No matter which CDN provider you are using. The configuration would always be the same.

For example, if you are using the FlyingCDN, all you need is the unique API key.

On the other hand, if you are using Cloudflare Free or Cloudflare APO (which is what most small bloggers and businesses use), you do not need to configure anything.

The plugin will take care of the content delivery without any extra customizations. Now, if you are using any third-party CDN service like BunnyCDN or KeyCDN, you can choose the first option, enter the CDN URL, and choose the file types you need to serve through the CDN provider.

Once you have finished setting up this CDN URL, you can move to the next configuration, which is database optimization.

4. Database

Database optimization comes with four sub-options.

• Automatic cleaning
• Post cleanup
• Comment cleanup
• Table optimization

Let’s take a look at each option.

4.1 Automatic Cleanup

• Auto Clean Database: Depends – You can set up the cleanup process according to your preferences. For example, if you are highly active with the website, setting up daily is enough. Alternatively, you can choose weekly or monthly options if you aren’t that active with posts or comments.

4.2 Post Cleanup

• Delete Post Revisions: Enable – If you are writing an article and need to save multiple copies, enable the post revision feature. On the other hand, you can disable it if you are running a one-page website.
• Delete Post Auto Drafts: Disable – You do not need to clean the auto drafts. Hence, disable this feature.
• Delete Trashed Posts: Enable – If you plan to remove all the trashed posts from the website automatically, enable this option.

4.3 Comment Cleanup

• Delete Spam Comments: Enable – If comments are marked as spam, FlyingPress will automatically remove them.
• Delete Trashed Comments: Enable – After you enable this option, FlyingPress will remove every trashed comment from your website.

4.4 Table Optimization

• Delete Expired Transients: Enable – There is no need to keep expired transients. So you can keep this option enabled.
• Optimize Database Tables: Enable – Keeping your MySQL database clean is mandatory to improve the website speed. So, enable this option.

If you need advanced database optimization features, you should use the WP-Optimize plugin instead of the DB optimization module offered by FlyingPress. I also use it, and here is a detailed guide on how to optimize WordPress database using WP-Optimize plugin.

5. Bloat

Next is the bloat optimization. Here, you will configure the main reasons for WordPress bloat and optimize them.

• Disable Block Editor CSS: Disabled – If you are using the Gutenberg editor, keep this setting disabled.
• Remove Dashicons: Enable – This will help you eliminate the CSS files loaded by admin icons or disable Dashicons on the front end.
• Disable Emojis: Enable – This feature removes a portion of JavaScript code from your website.
• Disable jQuery Migrate: Disable – Page builder plugins use jQuery for proper functioning. So, if you use any page builders like Divi Builder or Elementor, you must keep the jQuery Migrator feature. Getting rid of slow plugins is another option you can choose.
• Disable XML-RPC: Enable – XML-RPC is used for publishing posts directly from mobile. It is not optimized for speed or security. Most people (including myself) disable XML-RPC.
• Disable RSS Feed: Disable – When your website doesn’t have a blog page, you do not use an RSS feed. So, keep the RSS feed option alive if you publish articles on your blog.
• Disable oEmbeds: Enable – When you paste a YouTube URL, Spotify playlist, or Twitter post into the WordPress editor, the CMS automatically generates a preview of the embed. If you do not need this feature, enable this option.
• Disable WP Cron: Disable – WP Cron is a critical feature to run the website perfectly. Hence, do not deactivate it. On the other hand, you can also manually configure the cron job through a third-party service or your hosting. If you manually configured the cron job task, turn off the WP Cron feature.
• Limit Post Revisions: Enable – When you enable this option, only three post revisions will be saved to your MySQL database. This will help you with keeping your database optimized.
• Throttle Heartbeat API: Enable – Enabling this option allows you to limit background activity to once every 60 seconds.

6. Settings

The settings page doesn’t come with any optimization options. Instead, it gives the major plugin settings, which you can tweak.

The first option available is the license key management.

Since this is a premium plugin, a valid license key is required to receive future updates. Next, you have the import/export function.

If you need to export your current FlyingPress configuration to another WordPress website or import a third-party FlyingPress configuration to your current website, use this feature.

Finally, you have the option to purge the entire cache.

After a redesign or major change to the website’s design, purging the entire cache is ideal. Please note that this will temporarily slow down the website and serve uncached files to your website visitors for a short period.

These are the main FlyingPress configuration options you can use to achieve maximum website performance speed. To make things even better, you could pair FlyingPress with a performance optimization plugin like Perfmatters.

In the next section, we will see how it is done.

How to Configure FlyingPress with Perfmatters

Combining Perfmatters with FlyingPress will help you improve the performance of your website or online store. This way, you can easily boost the core web vitals, such as the largest contentful paint and cumulative layout shift.

Here, I am selecting FlyingPress as the primary performance plugin. Next, configure it like you usually do.

Next, keep these Perfmatters settings enabled:

• General Settings
  • Hide WP Version
  • Remove wlwmanifest link
  • Remove RSD link
  • Remove shortlink
  • Remove RSS feed links
  • Disable self pingbacks
  • Disable REST API when logged out
  • Remove REST API links
  • Disable password straight meter
  • Remove comment URLs
  • Autosave interval – 5 minutes
• Script Manager
• Preloading

Let’s look closely at Script Manager and see how it helps. After enabling the Script Manager option from the Assets settings, go to the front end of the website.

Now, you will be redirected to the script manager dashboard.

I also recommend enabling test mode from the settings.

When test mode is enabled, the changes will be only visible to logged-in admins. It won’t go public. This way, if any configurations can break the website, you can prevent it. You should also enable the display dependencies option to show all the jQuery plugins.

Now, you can disable specific script files from pages or entirely from the website. Here is an example. When you use a social media sharing plugin, you do not need to load the files all over the website.

Loading the files on blog posts or pages is acceptable. So, you could load them only on blog posts through the Script Manager settings.

This way, you can control the JavaScript executions on your WordPress website. This way, you can easily increase the user experience of your website by enabling full page caching and similar optimizations with FlyingPress.

Since the cache plugin is supported by most hosting providers, there won’t be any compatibility issues.

That’s it! You could check the before and after results to ensure the website’s performance is boosted. Use a performance monitoring tool like GTmetrix or Google PageSpeed Insights.

FlyingCDN — Why You Must Use It

FlyingCDN is an optional add-on for FlyingPress that uses Cloudflare Enterprise infrastructure to deliver your site content globally with exceptional performance and perform cloud-based optimizations.

Here are the reasons why I started using it instead of Cloudflare Enterprise or APO:

• Build on Cloudflare Enterprise’s premium CDN network with 310+ edge locations across 120+ countries for worldwide coverage.
• Full HTML page caching at edge servers with TTFB under 50ms globally.
• Cloudflare Polish & Mirage image optimization at the edge level.
• Automatic WebP conversion and image compression without changing URLs, so no need for an additional Image optimization plugin.
• Responsive Images (adaptive images) that serve appropriate sizes based on the device.
• Enterprise-grade DDoS protection and advanced firewall capabilities.
• Handle traffic spikes effortlessly through distributed edge caching.
• WooCommerce-ready caching that works with shopping carts and logged-in users.
• Argo Smart Routing for optimized content delivery paths to improve TTFB with Tiered Cache architecture.
• Brotli/Gzip compression to deliver compressed content saves bandwidth.
• Seamless FlyingPress integration with intelligent caching behavior.
• Costs only $5 per site per 100GB of bandwidth per month, much less than Cloudflare Enterprise and equivalent to Cloudflare APO.

These performance benefits help users typically experience TTFB under 100ms, significant Core Web Vitals improvements, and 30-40% faster loading times compared to standard CDN solutions.
