VMS is an
enterprise-grade operating system, designed for serious production work.
At the time VMS was conceived, Unix was a university product, used for
teaching and research, not for heavy production work.
In the mid 80s our Uni teaching 11/780 running VMS would groan and creak
under the strain of 50 students logged on. I was told that over at Sydney
Uni, their 11/780s were running a very modded and tweaked Unix and could
have a hundred or more students logged in on the one machine. Whether it
was crashy or not, they got more bang-for-buck out of their VAXen.
