Ok, I've now got the accelerator installed which works wonders, but I've still got a few questions.

Correct me if I'm wrong, but I assume that the Cache Hit Percentage is based off of how many hits to the board draw from the cache as opposed to having it generated from the files off the disk, and or a new post etc?

The second is where is this important? What are the implications? I know people say to keep it between 30-60%, I'm at 53% at the moment but is there a magic upgrade light that's going to flicker on at some point?

Thanks!
