Hyper Cache

Extremely easy to set up. KeyCdn support works and now I hope Stefano will come up with Preloaded Pages one day. 
I had bought Rocket Cache, Comet Cache Pro (f.. up my Multisite twice, they refuse to refund). 

 

Best Caching Plugin IHMO

Super fast, not overly complicated but with enough settings to customize for any set up. Most importantly: works like a charm on VPS!

THE caching plugin

Really well coded plugin, improved pagespeed for google from 86 to 93 compared to lightspeed cache. Simple and reliable.

Simply faster

Hyper Cache is a performant and easy to configure cache system for WordPress.
