FWIW, I ran a make buildworld this evening on my UP1000 under iprobe, as well as with the receive side of a netperf tcp stream. (for anybody who doesn't know what iprobe is, check out http://www.cs.duke.edu/ari/iprobe) For the buildworld, the system spent about 40% of its time in kernel. Roughly 50% of that was in various states of idleness. I've left full reports at: http://www.cs.duke.edu/~gallatin/iprobe_current/ The "???NOT_FOUND" is userland code I didn't tell iprobe about.
