## WP Rocket or LiteSpeed Cache

1. Add the plugin from the WordPress dashboard.
2. Activate it.
3. Configure caching and optimization settings.

**Setting tip:** only enable JavaScript defer if the site's functions still
work correctly with it on. **Alternative:** LiteSpeed Cache, specifically for
sites on LiteSpeed servers.[^iskills-course-notes]

## Perfmatters plugin

A lightweight performance plugin with three core features: disabling unused
scripts, removing query strings, and lazy-loading images.
