[vfio-users] Loading virtio modules on the host helps guest latency?

after fighting a lot with latency issues in my Win10 guest, I discovered
a small note in the Arch Wiki [1], suggesting I should load the virtio
modules for a remedy.

Sure enough, this helped.

Now I am dumbfounded, because I always thought that those modules are
only for guests, and not for hosts. I am looking for an explanation on
why this helps. Does anyone have knowledge to share?

Many thanks,
