[OT] best kernel scheduling patch for a workstation

Seome month ago I was reading about various realtime and low-latency patch for the kernel . It was noted in the article that the one the Author thought would make his X desktop zippy didn't, and the other one did. Now I can't find the article, and I also can't find the patches (though I admit I did not spend too much time looking for that patches). I'm just wondering what patches you guys find to be the most benificial for a workstation. JW
