4.2 and cheap LAN connections and later WAN connections drove the hockey
stick - no doubt and your are right, until the Stream networking work
(which was originally Steve Rago and the folks in Summit, IIRC), PWB 3/PWB
4.0 and later the commercially System V was definitely at a huge
disadvantage and even when the Streams networking code shows us, the
performance was not nearly as good plus by that time, all the code had
started to assume sockets (and sockets had been ported to DOS), so Streams
was still born.

I'm asking 32V vs
4.1

BSD had networking. Once you had that, you
don't look back. Sys V (and
prior) so far as I know, didn't get networking until Coherent did their
STREAMS stack that somehow ended up at Lachman - I ported it to a crazy
super computer and to SCO Unix. SCO was pretty stock AT&T code and let
me tell you, it felt pretty crappy after having used BSD and then SunOS.
It was a giant step backwards.
I just think the BSD folks were moving forward faster. Rob with start
talking about cat waving its tail, I get it, not everything was better
but a lot was. Solid networking that performed was very pleasant.

Paul,
You got me thinking and I'm curious if anyone really knows historically
how
many sites ran a 32V system? In those days
(late 70s/early 80s) the
universities that knew and and even many sites inside the Bell System,
the
Vaxen I ran 4.1BSD (say the Marx's brothers
at Whippany along with the
Vax
in the underseas research lab were we put the AP
I did for my thesis).
There were a couple in Summit I know, and probably Homdel and I'm
guessing
in some of the operating companies, but I never
got the feeling 32V was
popular. The folks with Vaxen that I knew, if you were able to run BSD
(4.1 and eventually 4.2), did. Later on the only non-'pure-joy'
systems
I
knew were a couple of Ultrix systems because they
wanted the support
from
DEC and IIRC were using FORTRAN and wanted the
DEC compiler which only
ran
on Ultrix or VMS. Inside of AT&T, I
personally think I knew more folks
with VMS (Fortran being the key anchor) than those that ran 32V.
