I think part of that is due to the effecient UDP protocol Rocke devised.
For this application UDP rocks (no pun intended) compared to TCP. It also
requires a lot less work on the part of the server and TCP/IP stack,
as well as less traffic. Let's see, send a single packet to the server when
completing a block or starting a new run, and receive a single packet
response from the server. Very effecient and well thought out. I'm now
on Bovine, but they don't have a working proxy, nor even a SunOS proxy (which
would be perfect, since only a few SunOS machines here have socks access
through our firewall).
