Currently I have a wordpress site and am using this plugin. Without the plugin my website takes 2.1 seconds to load using http://tools.pingdom.com/fpt/ test from Amsterdam, Netherlands and has a performance grade of 76/100.
With this plugin I was able to increase the performance grade to 94/100 using Minify, Object Caching and Browser Cache. Unfortunately the loading time of my site now take 6.8 seconds, from which 5.3 seconds is waiting for the initial connect. This used to be 0.4 seconds.
I have contacted my hosting admin and they say there is nothing wrong with the installation of xcache and that it works fine on other accounts. The problem seems to be W3 Total Cache.
xcache server settings
Does anyone else have this problem and does anyone have any suggestions on how to fix it?
