Correct me if I'm wrong again, but I thought that RFC 1122 mandated
following Jacobson'88, which specifies that specifies that packet
loss, as indicated by timeout, should result in setting the CWND to
its initial small value.  I also thought that Reno retransmits before
timeout (less conservative) and consequently only halves the window
(less conservative).

If the changes made transmission slower, why were they adopted?  If
they made it faster, perhaps I'm misinterpreting "conservative".

Cheers,
Lachaln
