I think you are moving away from the scope where freebsd-net is the correct= mailing list.=20 There are literally thousands of research papers comparing congestion contr= ol algorithms and other TCP improvements. I suggest you check some of those= (Sally Floyd's papers http://www.icir.org/floyd/ are still a good starting= point) and read up on what the ICCRG has done: https://irtf.org/iccrg Lars=
