  Thanks for suggestion. I've just tried it, performance difference is
indistinguishable.

  Well, I'm aware of this feature. I'm just evaluating performance of RELENG_6 
systems on uniprocessor i386 system, and (for now) it's significantly worse
than under RELENG_4. So I've used fxp just for comparison (and to rule out
possible specific regression in rl NIC driver), not for anything more
serious.
