After reading this thread: http://tomatousb.org/forum/t-267882/ , I've come to the conclusion that all(most?) flavors of tomato use TCP Reno to handle any potential congestion with TCP Vegas available as a hidden setting(nvram variable(s)). My question is: Why only those two? TCP Vegas and Reno tend to perform similar in my experience. The interesting ones are TCP Westwood(excellent performance over WiFi in my experience) and TCP Hybla(for satellite links).
