I am slowly working the performance bottlenecks out of my rack, and ran into this puzzling scenario.

Ovirt shows CPU usage at over 50%.

Windows shows CPU usage between 5 and 15 %

The backing store is TrueNAS NFS on a 10 GBit lan. I am seeing just under 1 GBit throughput on the storage network for this operation (create database).

Am I reading this correctly that my system is bottlenecking on the CPU used to handle the Windows disk IO over TCP/IP ?

Thanks
