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. -- Will
