Performance metrics vary between active lab machines #221

Description

@ProjectsByJackHe

From many recent Secnetperf runs,

there is a noticeable performance difference between some lab machines --- even though the code is the exact same, BIOS configuration is the same, SR-IOV is both enabled...

For example, in this run: https://github.com/microsoft/netperf/actions/runs/11565315387/job/32192210637,
lab machines 05, 10 were assigned for this windows iocp test job (WIN-2CSMQHE8ML4)
And were able to get sub 20 Gb/ps throughput on tcp + iocp.

But in this run: https://github.com/microsoft/netperf/actions/runs/11564283006/job/32189283432
lab machines 25, 26 were assigned for this windows iocp test job (WIN-B9SEU47NHOT)
And we were getting sub 9.8 Gb/ps throughput on tcp + iocp.

This is also true comparing the lab machines hosting the static lab VMs and the dynamic lab VMs from the stateless lab . (lab machines 42, 43)

We need to investigate why performance data is so different between the static lab, and the stateless lab .

This unblocks #73
