Something that I tried out last night that seemed to help my performance, but goes against the tweaks made in RubiX.
After Droid Overclock was updated, I tried out some of the advanced settings. After setting Sysctl (I'm not even sure what those tweaks did, to be honest) according to the other thread on DroidForums, I played around with "Up threshold".
I noticed that the default was set to 86. As I increased it toward 100, and eventually set it at 100, the phone got noticeably slower. Scrolling was choppier and menus were "heavier". So I tried what logically came next: I decreased the "Up threshold". The more I decreased, the faster it got. I'm sitting at 5% now and the phone is the fastest it's ever been (no, not a placebo effect).
When I tap on an icon, the app instantly opens. Menus feel super light and I can zip right through them.
Just my 2 cents.
EDIT: The only problem though, is that the threshold resets to 86% if you completely close Droid Overclock or if it FC's.
