List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 02 Oct 2014 08:06:38 -0000 Hello I have a few bhyve instances running that all seem to have a higher load average than what would seem normal for a system that is idle. The host is running FreeBSD 10.1-BETA3 #2 r272300. FreeBSD 10.1-BETA3 #2 r272300: Tue Sep 30 16:26:53 CEST 2014 root@trill.borderworlds.dk:/usr/obj/usr/src/sys/GENERIC amd64 FreeBSD clang version 3.4.1 (tags/RELEASE_34/dot1-final 208032) 20140512 CPU: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz (3411.56-MHz K8-class CPU) Origin = "GenuineIntel" Id = 0x206a7 Family = 0x6 Model = 0x2a Stepping = 7 Features=0xbfebfbff Features2=0x1fbae3ff AMD Features=0x28100800 AMD Features2=0x1 VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID TSC: P-state invariant, performance statistics The guests are all running FreeBSD 10.0-RELEASE-p9 updated via freebsd-update. The head of the top output inside a guest: last pid: 6109; load averages: 0.41, 0.38, 0.39 up 1+14:27:48 09:56:25 24 processes: 1 running, 23 sleeping CPU: 0.0% user, 0.0% nice, 0.0% system, 0.0% interrupt, 100% idle Mem: 6392K Active, 437M Inact, 379M Wired, 420M Buf, 3120M Free Swap: 4096M Total, 4096M Free I would have expected a load average around 0.00. Am I doing something wrong or is there something else that could be causing this? The guests all seem responsive and otherwise work fine. Apart from this I haven't encountered any problems when working with bhyve. It's nice and easy to work with. Thanks a lot for bringing this to FreeBSD. -- Christian Laursen
