Another thing worth note is what version of the kernel you are running versus how updated X is. I noticed when I migrated to libxcb under a 2.6.27 kernel that X starts running much more slowly for strange cases (like when audio is running, for example, X hogs the processor). I don't have a lot of insight as to how to determine which program makes X run hot, except for running very few things in X and starting a program and keeping an eye on something like top. But, in any case, another solution may be to keep the kernel updated if you are running the latest X software. ~daid
