I'm running compiz. It works very well, but I have noticed that under heavy load, such as whilst I am "making" something, the desktop gets rather sluggish. I have also noticed if I run make (or whatever else takes a lot of cpu) with low priority (i.e. "nice -10 make") the system remains fully responsive. So, I was thinking, instead of running everything else with a positive nice value, which is difficult to arrange, why not run compiz with a negative one .... So thats my reasoning.... Maybe my idea is flawed ? cheers Chris
