I tried SCHED_ULE, but got no difference:
Did you see no change in throughput, or no change in reported CPU use?
No significant changes.

We should probably take this thread to performance@ and get Kris involved. He may be interested in trying to reproduce your workload in our testbed so we can perform measurements of our own, as well as getting you to provide profiling information. One of the things we'd most like to have are nice potted benchmarks for real-world workloads, as that allows us to easily replay them, perform measurements, optimize, etc.
I can provide all profiling or configuration information you ask for. Except I can't provide PHP site source codes.

Now I'm in situation that I can't install FreeBSD on all new servers because they are all based on 2xquad-core processors and I can't be sure it would work good.

With best regards,
Alexey Popov
