Results ---------- First I want to show my appreciation to Daniel and Andrey. So thanks... I've implemented Spice, removed the touchpad and implemented enlightenment timer... PCVIRT1 with Windows 8.1 is on 5% host CPU usage... (OK) CmsrvAPP2 with Server 2012 R2 is still on 50% (Bummer...) A new freshly installed Server 2012 R2 with nothing activated or installed on gives 12% (Not completely happy) More tips are welcome.... See traceFlag T8038 section on https://pve.proxmox.com/wiki/Performance_Tweaks I've also noticed it on other sources... On the CmsrvAPP2 the SQL server is a SQL essential, so I have to figure out how to set the traceFlag on a SQL essential... -----Oorspronkelijk bericht----- Van: Daniel P.
