Why is remote desktop so much faster (clicking UI elements, dragging/dropping, even the Start Menu opening/searching!) to the HOST OS, instead of to its virtual machines?
With several servers that I've connected both to the HOST OS and Guest OS in many Hyper-V setups, the virtual machines all seem very very slow while the HOST OS just flies, like it should.
The only thing I can figure is in all of these environments (4 of them across 3 networks), they all share the same NIC between the HOST and all VMs, even though Microsoft's recommendation is to have 2 NICs - one for the Host OS, and one or more for the Virtual Machine(s).
If this is the case, I can test this easily on my home network where I have my home server with Windows 2008 Server R2 running Windows Home Server in a Hyper-V. But, I don't want to spend the money for a good gigabit card if that is not the reason - hence, the reason for this question.
Thank you in advance!
