Sorry to step in, but SO_SNDBUF and SO_RCVBUF are almost always bad for
performance, unless you know *EXACTLY* what you're doing at a packet
level. A general advice on a mailing list without VERY close analysis
of the network infrastructure and operating system behaviour is very
unlikely to help improve performance.
