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

Thanks for feedback Krzysztof and Alexandre. Below are the info:

I am using 1x 500GB WD HDD. I can add another one if that helps - something
like: WD5001AALS. Would that help? Where do you read the IOPS? and what is
a good number of IOPS today?

For VM I am using LOCAL QCOW2 - not sure how virtio drives work.

Hoping following info help you tell me if I am hitting a controller
bottleneck (meaning I can't help it) or if it is an HDD problem:
