Description Michal Skrivanek 2018-04-19 07:37:50 UTC
Current virtual-host profile doesn't match what RHV is using, based on Performance team recommendation we can update the profile to better values, and that would allow RHV to use the profile without further modifications

See https://bugzilla.redhat.com/show_bug.cgi?id=1564834#c8

Sanjay, do you think you can provide the final recommendation / set of changes?

Comment 2 Michal Skrivanek 2018-11-07 08:20:41 UTC
Sanjay, can you ack the changes you proposed in https://bugzilla.redhat.com/show_bug.cgi?id=1564834#c8 ? Or add anything else you'd recommend to tune?

Comment 5 Sanjay Rao 2019-03-06 20:13:56 UTC
I think after some back and forth, we agreed on changing the forced-latency to 70, which will pin the cstate to 3, which will prevent the host from going into deeper c-states and improve performance of VMs even when the host is lightly loaded. All other settings in the current virtual-host profile are fine.

Oh, ok. Thanks! That has already been done:
