Hi, I'm running compiz just fine on my FC6 system. However, I have noticed that under load (such as running make, yum update, my email client running a mail check or just my web browser running a heavy site) compiz becomes very unresponsive and thus also the desktop. I've also noticed that if I run the cpu heavy app. at an increased nice value, such as +15, compiz remains completely responsive whilst the apps runs pretty much at its usual speed. Unfortunately, its not easy to run everything at an increased nice value, so I wonder therefore, if it wouldn't be a good idea to something to run compiz (and Xorg or whatever it needs) at increased scheduling priority by default, to make use the user desktop always remains responsive ? cheers Chris
