You're probably asking Ralf, but I might as well answer as well..
Not using realtime, all cpu/smp options look fine.
CPU is usually pretty idle. Hovering around 90-99% idle. But the load graphs clearly show a radical increase, where before things were pretty smooth, now they're erratic and much higher.
ps: we use linux, not freebsd.
