WPCacheOn – WordPress Caching plugin

I just made a review of different cache plugins and was very curious about this one.
I compared GMetrix results with Swift Performance Light and CacheOn did not have a good score for YSlow test (less than 80%). So I’m not impressed.

But it works without problem on the test site and options (very little) are very convenient to check. 

Better than no cache plugin but I think other well known plugins will do a better job with proper configuration.

A simple and lightweight caching plugin for WordPress that boosts website loading time and enhances performance scores on GTMetrix and Pingdom.
