...as to deliver a lot of little/medium sized files. But every transfer starts with the usual small window size. While this is good for internet connections it is not as good for only internal connections where the environment is sane. I have tryed to tune initial window size via /proc/sys/net/ipv4/tcp_congestion_control tryed already bic,highspeed and vegas. Some will increase the window size faster, but all start with same low window size. So i''m asking if there is a other way to eighter disable TCP slowstart completely or at least increase the inital window size. Thanks for any help,hint in the right...

Hi, I'm very interested in making SSH use UDP for large data chunks. Maybe you know FASP (https://en.wikipedia.org/wiki/Fast_and_Secure_Protocol), but that is proprietary, although the website says it's based upon open source methods.
