Highly configurable, solid performance

The only hesitation I’d have in recommending this plugin is that its extensive array of configurable features is probably beyond the technical know-how of a novice user – a full-featured “easy mode” (or, better, a “learning mode” which automatically trains up a working configuration by observing server environment, site traffic patterns, and existing plugins) would remove that hesitation though, if you’re capable of RTFM’ing, you’ll have no trouble with this great plugin.
