SubjectRe: problems achieving decent throughput with latency.

Also, if it's as simple as allocating a few more buffers for tcp, maybe we
should consider defaulting to higher in the normal kernel? (I'm not suggesting
**my** numbers..)

The current values are the only "safe" defaults. Here "safe" means
that if you have thousands of web connections, clients cannot force
the serve to queue large amounts of traffic per socket.

The attack goes something like: Open N thousand connections to
server, ask for large static object, do not ACK any of the data
packets. Server must thus hold onto N thousnad * maximum socket
write buffer bytes amount of memory.
