The best. No other tools needed.

After issues with certain other caching plugins which require other optimization tools to work with them, as well as manual changes to .htaccess to derive the benefits needed for good Page Speed and YSlow scores, this plugin does it all for you. No need for any other optimization tools. I found some of these actually slowed down page load speeds. The pro version optimizes images too so no need for other plugins either.

Keep up the good work!
