Find the source of the congestion control loss in performances.
#438 (closed) document says the congestion control loss 15%. The ticket is about finding why/where.
The obvious way is to profile the server code with and without congestion control.
If you need help (I have currently a fast and a faster boxes on a gigabit switch) please discuss:
- configuration to check (memfile? etc)
- perfdhcp arguments (and goal, for instance 10% loss rate)
- profiling tool setup (macOS/Xcode instruments)
Next step could be to improve code to reduce the gap and/or to make simple the server faster.
