I have a small lightly trafficed personal site I set up some years ago to stay in touch with friends and family out of state. Lately I noticed a significant slowdown in loading my site, and logging in was absolutely painful. At first I blamed my hosting company. Then I decided to deactivate this plugin. VOILA, my site is fast again.I load quickly, logging in is quick, and I apologized to my hosting company for complaining. Maybe there is some advantage to this plugin. But for my small personal blog, the disadvantages out-weigh any advantage it may have.
