Don't get
me wrong. VMS is a fine system, and for some applications
it's superior to unix. But that doesn't mean I have to like it for
what I want to do.
In what sorts of things might it be considered superior?
Well, it's been a while since I played with VMS, but....
VMS is generally far better at keeping independent users from
interfering with one another through exhaustion of common resources.
The VMS privilege model is immensely better than the Unix one (much
finer-grained).
VMS has better support for structured files of various sorts, and,
while I've never measured it, I suspect VMS's performance is better
when dealing with very large directories (tens or hundreds of thousands
of entries in a single directory).
There are various epiphenomenal differences as well (such as the
support for various languages), but those are really differences in
the support infrastructure rather than differences in the OSes proper.
