I have tested the RO server requests pr. second response with a RO.Net and a Delphi 10.1 RO server. Both were using your Http.sys servers and in the Service Tester I was using the WinINetHttp client channel. I used Oxygene on the .Net side.
In the Service Tester I was running 50 threads and 200 requests each.
This surprised me as I would have thought a natively compiled Delphi server would perform much better.
Is performance difference a result of different coding practices between the different platforms or that .Net just performs better?
