In fact, this plugin is awesome. Previously I installed other cache enhancement plugin. It did run 2.6 to 4 seconds or more to fully rendered my website.
Then I start this plugin. Excellent, it only takes 1.1s.
There's no tweak to the setting, yet, but it runs super fast. Just as the tagline, speed w/o compromise. Runs on wp 3.3.1 this plugin work w/ ease.
