Benchmark data on BizTalk 2020 Virtualization

I have seen many customers move from very fast on-prem SAN to slower virtual/cloud disks having performance problems. Usually CPUs are ok as long as you don't share CPUs with lots of VMs. So I would benchmark during load tests the old on-prem disk performance and then compare the virtual/cloud disk performance. In SQL you can also check DMVs for read and write storage latency, which also give good insight. Usually on good systems I see, it is less than 5ms under load.
