This plugin allows your WordPress blog to output pages compressed in gzip 
format if a browser supports compression.
HTTP compression generally means a 60-80% REDUCTION in the size of your pages 
(broadband usage) as well as an INCREASE in download speeds of 3x to 4x.
To test if your blog is using compression use the following link:

Check “Page GZip” on the right hand size. 
Check “Bandwidth saved by compression” on the left hand side.
NOTE: This plugin should not be used alongside WP Super Cache or WP Cache 
since those plugins are already implementing compression. Your blog 
will keep working but those plugins will stop caching new pages.
