It should be noted that slow-start is not just used for starting up a
connection. While this may not be a large issue for many MUD implementations
either, slow-start will also be involved for already-open connections under
some congested network conditions (if packets start getting dropped). Even
with persistent connections, therefore, this behavior can cause connection
performance to deteriorate even worse under already bad conditions for anything
which needs to send large amounts or bursts of data.
