Hmmm. Without that option enabled the system was a slug, forums, ACP everything.
But hey, if the pages display in < 1 sec with it on -vs- > 2 minutes with it off...
load averages with it on and off were noticable, we saw 60 to 80 percent CPU loads on the machine (peaks) with it off, now the system loafs along barely breaking a sweat. I doubt we see more than 10 to 20 percent load at our peak period.
