I've noticed some "scheduling" strangeness on 2.1.x kernels too.
2.1 seems to schedule some things differently, so that when I move a window about, it sometimes lags behind in a way that it didn't do on 2.0 kernels. This makes it feel sluggish. It may actually be scheduling something faster so that this increases the workload.
I also kill the RC5 client when I need disk intensive jobs done. It seems to slow stuff down, because the rc5 client sometimes gets scheduled when a disk-IO is done.
Vague impressions, not backed up by numbers. Feel free to try and benchmark some of my vague impressions....
