I'm helping someone trouble-shoot a sluggish Windows 11 VM running
under bhyve (FreeBSD 14.1) related to the number of vCPUs. With 1-2
vCPUs, the VM's performance is reasonable, but adding 8 or more vCPUs
makes the VM nearly unusable because even moving the mouse takes minutes.
Before I dig into this, do these symptoms sound familiar? I did find a
mention on the wiki (1):
Only one or two VCPUs should be used during installation but this
number
can be increased once Windows is installed
Is there something missing from bhyve's emulation that causes this?
TIA

Hi!
I am using Win10 on bhyve (FreeBSD 14.1-RELEASE-p5) with 20 vCPU and no
problem here..
I would suggest first going back zu 2 vCPUs and updating all related
drivers (bhyve-virtio*...) and let windows doing its internal things
like searching for updates...
How are you accessing the vm, via VNC or RDP ? Maybe theres some network
problem..
just my 2 cents..

Stephan
