I was a bit worried about purchasing and not seeing a noticeable speed difference but this plugin is unbelievable. You will notice in seconds a huge improvement particularly if you have lots of plugins installed and a busy main page. Highly recommended! A must have for any serious site.
There is no bugs anymore !! Great Developer to make incredible powerful plugin !! If you want to save your money to upgrade your server, you can purchase this 0XART Speed Optimizer plugin. It is probably the best plugin that I have ever used. I do recommend this plugin to everyone who want to speed up your site and make your members feel much better !!
Ask if you are having problems I was and after the developer check out my issue, updated the plug-in for me and told me which other plug-in was conflicting all was well and fixed. So, If you are having problems it's most likely not this plug-in so please ask the developer.
I didn't run any official speed boost, and I didn't need to. Knowing my site's performance as well as I do, the boost in performance and speed was noticeably significant. I didn't need to a test, I could see it with my own eyes. There were only 1 or 2 very minor anomalies that occurred after I installed the plugin on my site, but they were easily corrected in minutes. The site runs as it always has, only FASTER! Very good plugin, and reasonably priced for the good it does.
