You're probably asking Ralf, but I might as well answer as well.. CONFIG_HZ_250=y CONFIG_PREEMPT_NONE=y 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. Cor ps: we use linux, not freebsd.
