image Speed up your WordPress Blog in the quickest and best possible manner including Server side and client side improvements via this plugin named Web Optimizer, from the description on the plugin page and it’s presence on the Google code repository It  made me firmly believe that this plugin will surely get the task of Speeding up and Boosting slow loading times a easy job for any novice user , as it has all the characteristic of a Server side and client side optimization routine .

On Server side

it compresses pages and uses gzip compression if supported  , also It tries to make CSS sprites which get loaded quicker on the client side , it also employs various Apache hacks and htaccess tricks to get the task done .

On Client side

it minifies CSS and JS and also optimizes HTML

Feature list is exhaustive and enthralling , take a look and be tempted to use it

Note –

If you use Wp-Cache or Wp Super cache disable them before using this and they may conflict as both essentially do the same on server side stuff while this Web optimizer does various client side optimization too .
