LiteSpeed Cache is an all-in-one site acceleration plugin, which includes a collection of optimization features.
Things to keep in mind:
- Only offered by some web hosts (as far as we know: WPopt)
- Lazy loading is handled better by Lazy Load by WP Rocket (https://wordpress.org/plugins/rocket-lazy-load/)
Recommended settings:
- Enable “CSS Combine” and “JS Combine”
- Increase “Max Combined File Size” to 5 MB
