I've just installed a couple of FreeBSD 10-R instances on our Xen pool. The load averages on these machines seems to run higher for an idle box, than FreeBSD 9.x did e.g. 10.0-R (amd64 GENERIC): last pid: 4219; load averages: 0.31, 0.23, 0.12 up 0+00:07:45 14:04:08 15 processes: 1 running, 14 sleeping CPU: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle Mem: 16M Active, 15M Inact, 44M Wired, 20M Buf, 1893M Free Swap: 2046M Total, 2046M Free A 9.2-STABLE (amd64 XENHVM) instance on the same XenServer: last pid: 76440; load averages: 0.00, 0.00, 0.00 up 2+15:07:27 14:05:10 22 processes: 1 running, 21 sleeping CPU: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle Mem: 13M Active, 128M Inact, 91M Wired, 59M Buf, 237M Free Swap: 494M Total, 494M Free Both have xe-guest-utilities installed. The second box is actually technically busier than the first (as it's routing traffic between it's interfaces - admittedly, not much). But the load average on 10.0-R never settles to zero (like it did for 9.x) Just a bit confused as to if the user, nice, system and interrupt times are zero - how can the LA be >0? Anyone else noticed this? - I know an LA of 0.31 isn't the end of the world - but it's a bit of a jump on 0.00... -Karl
