They changed the calculation of TCP buffer sizes. I think the point was to make better use of available memory. If there's plenty of memory, then Linux can afford to allocate a large buffer so that the sender can keep the pipe full of packets, and a large buffer requires a large scale factor. But the larger the scale factor is, the more hindered the communication is when these broken boxes mangle it. If a small scale factor gets mangled, your buffer will seem smaller than it is but the connection can still limp along. If a large scale factor gets mangled, the connection freezes completely. -- Bj�rn Persson PGP key A88682FD omb jor ers @sv ge. r o.b n.p son eri nu
