Should also mention the kern.sched may be playing a part in this too.

Hi!
Can you try with this settings:
op@opn ~ sysctl kern.sched.

kern.sched.name: ULE

Summing up for the record, in my original test:
1. It doesn't matter whether X is running or not.
2. The problem is not limited to two or fewer CPUs. (It also happens
for me on a six-CPU system.)
3. It doesn't require nCPU + 1
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
