Indeed. RSTS/E did better, with less hardware -- 64
users on an 11/70 was no problem, and earlier on you could run 16 users on an 11/20
(though not all that comfortably).
It all depends on what the users are doing, of course. When I went to
school back in the late 1980s, the main computer was (for a while) a
VAX-11/780. Things started to get dodgy with 30 engineering students
online compiling and running crap code, and almost useless when 35
were on.
There was also an ancient PDP-11/70 that ran some variant of Unix, and
that general became useless after about 10 students were online.
