I've installed a number of FBSD10 boxes recently, and they all seem to idle at around that (even when doing absolutely nothing) - I did post about it and was told it was just cosmetic... It certainly seems to be cosmetic. If it's the same issue - I'd guess it's not bhyve related... " last pid: 1294; load averages: 0.42, 0.32, 0.27 up 1+20:44:55 11:47:16 18 processes: 1 running, 17 sleeping CPU: 0.0% user, 0.0% nice, 0.0% system, 0.1% interrupt, 99.9% idle " That's from a bare metal amd64 10.0-RELEASE-p9 box with no services / users on it. Thinking about it - we had the same 'symptom' on a Xen based FBSD 10 box as well... -Karl
