I run a Win7 VM on a i5 gen 4 ULV machine. I have always had problems
with lag increasing over time. On bootup the VM is fast, but after 20
min it is unusable with each screen redraw taking ~4 sec and associated
high CPU usage. This has happened both on R3.0 and R3.2.

I work around the issue by using Remmina (or other RDP client) in an
appVM, and allowing IP forwarding in the firewall vm. This solution does
not suffer from increasing lag, and should be usable for everything
except gaming. See instructions here:
