Yes they are with the CPU overclocked. I have verified the results
when not overclocked as well (running at stock).

I'm sure disk I/O is a factor here. ULE is supposed to provide better
interactiveness during high load (and I/O load), right? Perhaps the
scheduler is being too liberal with time slices for I/O?
