I've noticed that using the Fedora 1 kernel (latest update) the scheduler is pretty bad when there are two nice 0 processes competing for CPU. For instance, if I have a CPU-intensive job running at nice 0, then nfsd processes run really slowly. Also logging in takes an age. It's much worse than the kernel in RedHat 7.3. Also xmms skips pretty badly when scrolling in acroread. Is this due to some sort of interactivity boosting? I think the kernel is very confused over which processes it needs to boost. Is there anything I can do to fix this problem?
