TCP problems with large window sizes on FreeBSD (GigaTCP)

2001-08-01 Thread stanislav shalunov
We want to build two or more machines that would be capable of achieving TCP throughputs of 700-800Mb/s over WAN (with a single TCP connection). The motivations of this exercise are spelled out on the referred web page. Additionally, I believe that getting through with this exercise with FreeBSD
