Erm, just as a random question - since device drivers (and GEOM) run as separate threads, has anyone looked into what kind of effects the scheduler has on these?
I definitely have measurable throughput/responsiveness differences between ULE and 4BSD (and preempt/non-preempt on 4BSD) on my MIPS boards when they're bridging traffic. I wonder if there's something strange going on with the scheduling and preemption of driver netisrs, taskqueues, the fast interrupt handlers, etc. This may -not- be a userland specific problem..
