Caching makes your website faster by storing frequently accessed data so it doesn't have to be generated from scratch every time.
Toggle opcode caching on or off for your website from Developer Tools. This caches compiled PHP code in memory, so PHP doesn't have to re-interpret your scripts on every request.
Enable or disable Redis on a per-website basis from your website dashboard. Redis caches database queries and PHP objects in memory, which significantly speeds up dynamic sites like WordPress.
Each website gets its own private Redis instance.
If your site runs on LiteSpeed or OpenLiteSpeed, install the LiteSpeed Cache (LSCache) plugin in WordPress for the fastest possible performance. LSCache can deliver cached pages in under 10 milliseconds.
Browser caching tells visitors' browsers to store static files (images, CSS, JS) locally for a set period. Configure this through your .htaccess file.
