[PVE-User] Very slow install of applications in Windows 2008R2 VM on Proxmox - What is the cause?

Hi Everyone,

I am seeing very slow install of applications within a Windows 2008R2 VM
that I built with 24Gbs of RAM (no users on it yet) and the Proxmox server
is a DL160 G6 with Dual L5520 Xeon quad core CPUs. I don't see why this is
acting so slow. I am looking for suggestions on how to make this work
faster.

Below are my findings of IO stats and HDD specifications. I would like to
know if there is any hope to this server. I am running Windows 2008 R2 in
IDE0 and QCOW mode.
