How does the fellow doing the acking know that slow-start has finished?
:o)
We've thought about ways of infering this and of adding reliable
out-of-band signaling for this - but the former complicates the otherwise
simple receiver, and the latter requires machinery that doesn't already
exist (options are not sent reliably).
Actually, if you prematurely leave slow-start (more common than not),
growing your cwnd more aggressively in congestion-avoidance can provide
a substantial performance gain (if it doesn't otherwise get you into
trouble);
