I'd done that for a day or so back a while ago. Looked for paging, any weird amounts of interrupts, etc. Never saw anything spike. I had the same thing running in a window next to it on my workstation, and my workstation was consistently doing more work, more swapping (linux netscape with flash plugin = 80+ MB), more interrupts on lesser hardware with the load rarely hitting 1.0+... I'll poke around with DDB more tomorrow and see what I can see in the ps output there...
