Well, the Windows 10 libvirt guest is installed locally in the laptop host itself, and I use a network cable for it instead of wireless to access the Proxmox guest.
So overall this is a problem with current implementations of QXL and spice-server?
@Victor:
In your last message there was a "signature.asc" file attached. I'm totally new to mailing lists. What was that attachment?
Again, thanks all for your attention.

I don't think this is going to improve much if not nothing.
I have a SSD and a much more recent laptop. Windows 10 is slow using
local WiFi. This is caused by the graphic stack changes in Windows 10
and the way currently optimizations are done for QXL by spice-server
that actually are not much effective.

This is unfortunately the phase (login) most affected by these
implementation changes.
