Hi all,
I am making a few CPU benchmarks on an host equipped with a single 6c processor.
- CPU set with 1 core on 6 sockets : 5400 pts.
- CPU set with 6 cores on 1 sockets : 11800 pts.
Both setting were set to allow this VM to use an unlimited amount of CPU resources and with an high priority.
But what monitoring showed me, is that the multi-socket settings allow only a CPU usage of about 60% on the host while the multi-core use 100% of the host's CPU.
That explain the large result difference but why is that behavior ?
Thank you.
