1. Depends on your application. To avoid TCP window size related slowdowns,
it needs to be at least as large as the bandwidth delay product (multiply
bandwidth by RTT).
2. net.inet.tcp.*space affects the _defaults_. Changing them means that
you'll use huge amounts of memory even in places where it doesn't matter
(like ftp control connections).
Instead, use setsockopt with SO_SNDBUF and SO_RCVBUF where appropriate.
