If echo "1">/proc/sys/kernel/sched_compat_yield before starting volanoMark testing, the result is very good with kernel 2.6.24-rc3 on my 16-core tigerton.
1) If /proc/sys/kernel/sched_compat_yield=1, comparing with 2.6.22, 2.6.24-rc3 has more than 70% improvement; 2) If /proc/sys/kernel/sched_compat_yield=0, comparing with 2.6.22, 2.6.24-rc3 has more than 80% regression; On other machines, the volanoMark result also has much improvement if /proc/sys/kernel/sched_compat_yield=1. Would you like to change function yield_task_fair to delete codes around sysctl_sched_compat_yield, or just initiate it to 1?
