Was that 2.4 kernel a vendor kernel with the O(1) scheduler?
no, a kernel.org kernel. the 2.6 kernel is so much faster for this workload that I switched for this app and never looked back. I found that if I had 5000 or so idle tasks 2.4 performcane would drop to about a quarter of 2.6 (with the CPU system time being the limiting factor)
