Enable Gzip Compression in WHM
You can easily speed up your WordPress, Joomla, Drupal install by enabling Gzip via easyapache.
EasyApache is an easy way to enable Gzip compression and will bring your PHP script loading times down. Google Page Speed takes account of Gzip compression, so it is better to enable compression to get a higher grade and possibly better ranking in search engines.
Simply log into WHM and go to Main > Software > EasyApache
You can simply select the “Previously Save Config” which is the latest saved profile.The module you are looking for is called Deflate (mod_deflate) and isn’t included in the short options list you get to see when you first access the EasyApache! Mod_Deflate is found in the exhaustive options list as a built-in module that is waiting to be enabled! Enabling Gzip compression means enabling mod_deflate, saving and building the profile. Recompiling Apache will last about 30-60 minutes and you still have access to your websites the whole building time.
After having recompiled Apache and enabled Gzip you can test this at the link below
