Windows 10 performance


Oct 14, 2019
Hopefully you can help me get to the bottom of this. I've got a windows 10 guest with pass through and everything seems good except for glitchy gui performance. trying to track down the bottle neck is made worse because the task manager/peformance/resource moniter all just freeze strait away when you open the window. I mean the values about usage freeze, everything else is fine. So i can't really track down the choke point. Anyone got any ideas?

Thanks in advance.

There is another problem now, my memory performance is terrible. numa is enabled as I have a 2 socket system. but my numa misses are equal to my hits. hmmmmm, is there a way to capture the output that the script eventually sends to KVM so I can interrogate the numa settings it's sending. windows is showing the correct layout i'd expect, cores and ram split down the middle. but how can I tell how this is translating onto the hardware in terms of pined cpus and memory?

"qm showcmd <vm id> --pretty" is what is used to expose what the script is passing to the kvm cmd.
