60 us worst-case latency, now that's more like it.
Voluntary preemption sounds a bit scary though, as in, it may be burning up
too much CPU trying to reschedule.
I also wonder how many drivers need patching.
Here are some results for 2.6.8-rc2-mm2 + voluntary-preempt O3. As I
suspected, the latency is about 10-20% better than with the stock kernel
+ voluntary-preempt.
