About Solid Performance
From the official readme · v2.0.1Description
Site speed and performance optimization don’t have to be a complex task. With Solid Performance, simply install and activate, and the plugin will incrementally create static versions of each URL of your website for an instant performance boost.
How Solid Performance Increases Your Site Performance and Page Speed ✅
You’re busy, and you need to spend time building your website. In order to build well you need a solid foundation. Installing Solid Performance lets you optimize your site performance right away and start building sooner and faster without having to spend time configuring dozens of options.
A solid caching solution should not cause breakage with your favorite plugins. Solid Performance comes out of the box with smart plugin exception rules for pages that have dynamic content created by these plugins:
* WooCommerce
* GiveWP
With these smart defaults and page caching in place automatically, you can focus your time and energy on building and enhancing your website instead of struggling through dozens of caching settings.
What is Caching and how does Solid Speed leverage it ❓
There are several different types of caching
Solid Performance focuses exclusively on page caching, grabbing the HTML of your WordPress URLs and storing that in a secure directory. Then, when your visitors arrive at your site, the browser doesn’t need to run through PHP or hit your database again, it just serves up the desktop or mobile (if enabled) versions of static HTML, CSS, and JS files fast and simply.
How Page Caching Benefits Your Website Performance 🚀
As soon as you activate Solid Performance, your site will get an immediate boost. You’ll see benefits like these:
🚀 Improved site performance (content delivery speed)
🚀 Reduced drag on server load
🚀 Measurable, quantifiable stats: lower bounce rates and higher conversion rates
When a site developer or manager is able to improve site performance for a client (for example), they are able to provide improved SEO results and meet a widely accepted expectation that well-run sites do not have slow download or content delivery times.
Installation
There are several ways to install and activate Solid Performance for your website. Here are two of them:
Install Solid Performance via the “Add Plugins” screen
To install and activate Solid Performance via your WordPress admin area, navigate to “Plugins > Add New Plugin”. On that screen, go to the search field on the far right top of the screen and type in “Solid Performance” and hit Enter. The “Solid Performance” plugin should be your first result.
In the “Solid Performance” plugin card, click on the “Install Now” button. You’ll see the button change to “Installing”, then it will switch to say “Activate”, click “Activate”. At that point, Solid Performance is active on your website.
Lastly, navigate to the Dashboard, then navigate to “Settings > Solid Performance” and toggle the option to “Enable Page Cache”. Now your site is SOLID with Solid Performance.
Install Solid Performance via SFTP
- Navigate to wordpress.org/plugins/solid-performance and near the top right of the screen, click on “Download.” That will download the solid-performance.zip file.
- Unzip the file locally on your computer. That should give you a folder called “solid-performance” with all the plugin files. If there is a sub-folder in that folder also called “solid-performance” then we’ll use the sub-folder.
- Upload the whole “solid-performance” sub-folder to the
/wp-content/plugins/directory - Navigate to your WordPress admin area, and then to “Plugins”. You’ll see “Solid Performance” in your list of plugins, but it will not be activated. Click on the “Activate” link.
- The page will refresh automatically. Navigate to “Settings > Solid Performance”.
- Toggle the “Enable Page Caching” option.
Now your site is SOLID with Solid Performance!
Frequently asked questions
Will this help me pass all Core Web Vitals?

How does Solid Performance improve the performance of my website?

When page caching is enabled, the buffer generated by WordPress will be saved to separate static HTML files, one for desktop (enabled by default) and one for mobile (enabled in Settings > Solid Performance > Advanced), within the wp-content/cache directory.
