The problem is that vSphere >= 6.7 is required for async callbacks to actually do anything -- to be fair to VMware at least they don't fail against older versions, they just work the same as synchronous calls. I was testing against 6.5. Testing again with 7.0: with patch: 4m28.477s 6.6 Mbps without patch: 7m54.925s 3.7 Mbps Looking at the raw logs I can see that requests are now overlapping as I would expect. This server is remote so I didn't expect to get good absolute numbers.
