What you could do to help is you could give mav's latest ULE patches a try with your workload and could measure stock ULE vs. the patched one. http://people.freebsd.org/~mav/sched.htt40.patch I have tested it on head, it does apply to 9-STABLE, but i haven't tried to compile or run with it, but i think it should work.
