Just a point on the timeline....
I think somebody asked why his CPU load was so high on AMD running linux.
I've completed compiling a "fresh" linux-kernel on my Ubuntu 14.04
system, installed and rebooted it.
And where previously a Linux-kernel would drain the CPUs it got assigned
to the max... Aka 2 CPU would drive the load +2 and top would diskplay a
With the new kernel, that is no longer the case. On a idle vm the CPU
load is like 6-7%....
At the moment I'm running:
So somewhere in the interaction between bhyve idle detection and the
older linux kernel things do not match...
