Best WP Fastest Cache Settings for the Perfect WordPress Speed

Are you looking for the best WP Fastest Cache settings for the perfect page loading time on your WordPress website or WooCommerce store? If you are, keep reading this article. Here, we will show you the ideal configuration for achieving the right Core Web Vitals score.

Website speed plays a crucial role in user experience and search rankings. WP Fastest Cache is one of the most popular and effective cache plugins for WordPress.

With the right WP Fastest Cache settings, you can significantly improve loading times, Core Web Vitals scores, and overall site performance. In this guide, we share the best WP Fastest Cache settings to maximize speed.

Whether you are using the free version or WP Fastest Cache Premium, these proven configurations will help you reduce server load, enable proper browser caching, and deliver faster pages to your visitors.

First, let’s take a quick look at WP Fastest Cache and what it offers.

Why Do You Need a WordPress Caching Plugin

A fast-loading website is essential for user experience, search engine rankings, and conversions. Without a proper cache system, every visitor request loads your WordPress site from scratch. This increases server load, slows page load times, and hurts Core Web Vitals scores.

A good caching plugin like WP Fastest Cache creates static HTML versions of your pages and serves them instantly to visitors. This dramatically improves loading speed, reduces TTFB, helps with LCP, and lowers server usage.

Whether you use the free version or WP Fastest Cache Premium, proper cache settings can significantly optimize your WordPress site and give you an edge over competitors who ignore speed optimization.

What to Look for In a WordPress Caching Plugin

Choosing the right caching plugin is crucial for maximizing speed and performance on your WordPress site. Not all cache plugins are equal, so you need to know what truly matters before configuring the settings.

Here are the key factors to consider:

  • Page Caching & Browser Caching: The plugin should create static HTML files and support proper browser caching to serve pages faster.
  • Minification & Optimization: Look for safe minification of HTML, CSS, and JS to reduce file sizes without breaking your site.
  • CDN & Cloudflare Integration: Easy support for Cloudflare, Cloudflare APO, or other CDNs for faster global content delivery.
  • Image Optimization & Lazy Load: Built-in support for WebP images, lazy loading, and background images.
  • Advanced Features: Redis or Memcached support, preload options, exclude rules, and proper handling for logged-in users.
  • Ease of Use & Updates: Clean interface, regular updates, and good compatibility with popular themes and plugins.

WP Fastest Cache: An Introduction

WP Fastest Cache lite

WP Fastest Cache is one of the most popular and lightweight cache plugins for WordPress. Since its launch, it has helped thousands of website owners dramatically improve their site speed, reduce server load, and achieve better Core Web Vitals scores.

The plugin offers essential features such as page caching, browser caching, HTML, CSS & JS minification, Gzip compression, and CDN integration. It has both a free version and a powerful Premium (Cache Pro) version that adds advanced features such as image optimization, WebP support, lazy loading, and more.

The Ideal WP Fastest Cache Settings for WordPress Websites and WooCommerce

The plugin comes with options like:

  • Settings
  • Clear Cache
  • Image Optimization
  • Premium
  • Exclude
  • CDN
  • DB

We will explain the best configuration for each option below.

1. Settings

Here is the main configuration of WP Fastest Cache for the ideal website speed:

  • Cache System: Enable (You need to enable this option so WP Fastest Cache can start working)
  • Widget Cache: Enable (It is a premium feature, but enabling it can reduce the number of SQL queries)
  • Preload: Enable (You must enable this option so the plugin can automatically create a cached version of the website)
  • Logged-in Users: Enable (If you enable this, the plugin won’t show the cached version to logged-in users. It only serves the cached version to website visitors)
  • Mobile: Enable (You do not need to show the desktop cached version to mobile visitors)
  • Mobile theme: Disabled (You do not need this option right now. Also, it is a premium feature)
  • New post: Depends (If you publish posts daily, enable this option. If you are not that active with blog post publishing, you do not need it)
  • Update post: Depends (Like the last time, only enable if you are active with post updating)
  • Minify HTML: Enable (It will help you with the website speed)
  • Minify CSS: Enable (Like the HTML minification, CSS minification can be helpful)
  • Combine CSS: Depends (Test after enabling it. Sometimes, the website design can break if you enable this feature)
  • Minify JS: Enable (Remove the extra white spaces from JS files, which can help with the page load time)
  • Combine JS: Disabled (Enabling this will cause some issues, so we recommend keeping it disabled)
  • GZIP: Enabled (It will help with the overall website’s speed)
  • Browser Cache: Enabled (Highly recommended)
  • Disable Emoji: Enabled (If you are not using emojis on your website, you should enable this option)
  • Render Blocking JS: Enabled (It is a premium feature, but it is recommended for the best page speed)
  • Google Fonts: Enabled (Enable this option if you are using Google Fonts. This option will load the fonts asynchronously.
  • Lazy Load: Depends (If you are using a dedicated image lazy load plugin, keep this option disabled. Otherwise, enable it)
  • Delay JS: Depends (Check if the website is going to function properly after enabling this function)
  • Language: Depends (Based on your liking, you can pick a language)

2. Clear Cache

When you need to clear the cache, you come to this page.

clear cache

As you can see in the screenshot, you can

  • Clear all cache
  • Clear cache and minified CSS/JS
  • Add new timeout rules
  • Add new rules for specific pages
  • Do varnish cache

And so on.

If you are looking for a simple way to clear all the cache, you can hit the first or second button. The timeout rules will help you automate the task.

For example, add a new timeout rule.

add new timeout rule

Now, you can customize it further. If you are actively publishing, clearing the cache once a day is ideal. If you are not that active, choose a different interval.

Tweak the options as you need and save the settings.

3. Image Optimization

Image optimization is a premium feature offered by WP Fastest Cache. Without using any third-party plugins or hosted services to compress the image, you can use this built-in feature of WP Fastest Cache.

If you are a Lite version user, you can skip this. If you are using the Pro version plugin, click the Optimize All button and compress your images to save disk space and serve them faster.

4. Premium

Here, you won’t see any configuration options. If you are using the lite version of the WP Fastest Cache plugin, you can see the pricing here:

The plugin comes with a lifetime license. So investing in it is a good deal.

5. Exclude

Here, you can exclude specific pages, user-agents, cookies, CSS, and JS from caching.

exclude settings - WP Fastest Cache Settings

You can add as many pages, user agents, cookies, CSS, and JS to this wizard.

6. CDN

Using a CDN provider for your blog or WooCommerce site is highly recommended. It will make your website faster and safer.

cdn settings

The plugin can be connected with:

  • Bunny.net
  • Cloudflare
  • Others

If you use Bunny.net or Cloudflare, you have direct integration. All you need to do is enter your API token, and that’s it.

If you are using any third-party CDN provider, hit the other CDN provider option.

Now enter the CDN URL and Origin URL.

enter url - WP Fastest Cache Settings

Once you have done this, the CDN integration is successful.

7. DB

The database optimization is the last thing you can do. Without any additional database optimization plugins like WP-Optimize, you can let WP Fastest Cache handle the performance optimization.

Here are the things you could do:

  • Clean all the data
  • Clean post revisions
  • Clean trashed contents
  • Clean trashed and spam comments
  • Clean pingbacks and trackbacks
  • Clean transient options
  • Clean orphaned post meta
  • Clean orphaned comment meta
  • Clean user meta
  • Clean orphaned term meta
  • Clean orphaned term relationships

You can either clean these individually or hit the Clean All button to get rid of all the unnecessary data quickly.

Your choice.
