do a ps -aux and see if there are any process migration threads, if you do then its running the O(1) scheduler.

You really should try the O(1) scheduler. 600 process is a lot, we had ~100 for our benchmarks so it wasn't as big of a overhead for the old scheduler. (Running Itanium 2's didn't hurt either ;)
Your running Xeon's with more processes, you are more likely to see a benefit from the O(1) scheduler.
