:Matt, could you clarify. Is the patch that Dave applied to 4.2 applicable to
:4.4-RELEASE? It sounded like not. I applied the tcp_output.c and
:uipc_socket.c patch to my 4.4-RELEASE servers and it made a whole lot of
:difference, like 500KB/sto 954KB/s from my old P200 server to my laptop.

:Thanks.

Well, the patch is certainly relevant to 4.2, 4.3, and 4.4. Portions
of it are relevant to 4.1 and earlier. We've fixed it in -stable
(i.e. post 4.4) so if you are tracking -stable you already have it.
However, if you are running 4.4-RELEASE and haven't updated then you
don't have the patch and it is relevant. While it is a significant fix,
it is just one out of a number of fixes made since 4.4-RELEASE. The
easiest solution is typically to ugprade your machine to the
latest -stable. Unfortunately, upgrading at this exact moment could
be problematic as apparently a number of people are having problems
with recent IDE changes, at least judging by recent list postings.
-Matt
