Caching

Caching technologies store ready-made copies of pages or database results so a site answers requests faster and survives traffic peaks. The category includes server-side caches such as Varnish and Redis Object Cache, the WordPress plugins Litespeed Cache, WP Rocket, W3 Total Cache and WordPress Super Cache, and optimisation services such as NitroPack and Google PageSpeed. Most of these sites are WordPress installations whose owners have noticed slow pages and done something about it. The list suits hosting vendors with faster plans or managed caching, CDN and image optimisation services, WordPress maintenance agencies and Core Web Vitals consultants, since the owner has already shown that speed matters to them.
