For a typical mix of shell/edit/compile jobs on an 11/780, does anyone know how UNIX compares with VMS in terms of performance? By performance is meant response time and throughput time. I realize that this is an involved question, and that there are lots of other arguments in favor of UNIX. This is being done for a friend whose site is stuck with VMS. I would also like to know, if one OS is significantly better than the other, what the reasons are. Thanks. Glen McCluskey ..tektronix!mako!glenm

Boy, whenever the VMS vs. UNIX battle finally quiets down, someone has to stir things up again, let's try to be civil this time, after all, we all know you either prefer UNIX for the obvious reasons, or you defend VMS to justify your current predicament. ;-) Moss.

I don't have any exact figures, but from just general experience on a 750 running BSD 4.2 and a 750 running VMS, the VMS machine is significantly faster. I would guess that it is about 1.4 to 1.8 times faster in general execution speed. This is probably attributable to the faster file system and I/O system.

How about someone (or a group) take on the task of preparing the definitive
document comparing UNIX and VMS. Collect all the arguments made so far
and make the best cases for both sides. Then let's figure out a way to
keep it around (like in net.announce.newusers) and update it periodically.
