Hi Peter,

Confirmed. Running a bhyved 3-vCPU-"CentOS 6.5", the host CPU load for "vcpu 0"
is around 12% now. The remaining vcpus are all near or at zero load.

Ping times to the VM are fluctuating - ranging from 0.185ms to 35ms. "iperf"
throughput tests results around 700Mbit/s though.

Now it's time to scrap all ESXi hosts here... ;-)


Thanks a lot to you guys and regards,
Nils
