Bhyve - Windows 10 slower on 11.2 than 11.1

[xorus]

My Freenas build is on a PowerEdge T30 - Xeon E3-1225V5 - 16gb RAM. I run a Windows 10 VM with 4gb RAM and 2 cores, zvol on SSD, very standard setup. With the version 11.1, the VM ran smoothly. When I updated to version 11.2, the VM become very slow. I decided to reinstalled it but now, the VM is almost unusable. I also tried to install a Windows server to add more cores, but same result, it is very slow...

Any idea or tweak I could try to improve performance?

Thanks

Anything happening in /var/log/messages or /var/log/middlewared.log when the slowdown occurs?

I'll reinstall the VM and look at the logs, thanks.

I'll reinstall the VM and look at the logs, thanks.

I reinstalled VM Windows 10 yesterday, looked logs and found nothing that may explains the slowdown. What I noticed is that as soon as I try to launch an apps, the CPU usage is 100%, even for small task like opening the file explorer. I don't understand why it was running smoothly with version 11.1 and now with version 11.2 (latest update) it is so slow...

Same Problem here. I never used 11.1 and at the moment I am using 11.2-U3. Windows 10 VM is almost unusable. Every little action is pushing the CPU to 100%. Linux MINT VM is also quite slow but not as bad as Windows. Docker VMs are running fine. It seems to me that this maybe related to VMs using a GUI.

Same problem here. Windows 10 VM is running very slow in BHYVE.
Any suggestions?

Hard to tell what is going on without looking at a debug. If you decide to make a ticket at bugs.ixsystems.com, post the issue number here.

Are any of you able to confirm you still have the VNC device on your VM?

In older versions, this was causing high CPU at idle.
