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 200% cpu.

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...
