LightSpeed Cache (LS Cache)

What is LightSpeed Cache?

LiteSpeed Cache is a free, all-in-one WordPress optimization plugin that delivers powerful server-level caching and performance enhancements. It includes features like image optimization, CSS/JS minification, lazy loading, and support for QUIC.cloud CDN, making it ideal for boosting page speed and Core Web Vitals. While it works best with LiteSpeed Web Server, many of its tools are compatible with other servers like Apache and NGINX.

We only use this for websites hosted on WHC. However, it works well elsewhere too.

Install & Activate the plugin

Name: LiteSpeed Cache
Author: LiteSpeed Technologies

Here's how we configure the plugin:

The easiest way to configure the plugin is to head over to the "Presets" tab in the plugin, where you can apply a preset configuration that might suit your needs. 

The Aggressive preset is closest to how we would usually configure an optimization plugin. It minifies and combines both CSS & JS, optimizes static files, optimizes images and has a good caching configuration.

We don't use this CDN tool. It could be useful, especially with the Cloudflare option, but its not something you need to turn on.

3. Image Optimization

5. Database

Manage

The database options are mostly for reactively cleaning databases once they're bloated. If you ever need to do one-time database cleanup, this is a great tool.

6. Crawler

We can set limits on crawl bots set by search engines in this tool. No default settings need to be set. If you have an e-commerce site that seems to be running slowly, I recommend setting limits. We've seen issues before with WooCommerce sites crashing when they're getting crawled.
