Summary: What Cyber are you talking about?

What?  Are you saying that you are using a Cyber system that can handle
700+ users at a time?  My experience with a Cyber is with a machine that
dies a horrible, crawling death when 125 users get on it.  With this number of
users, the machine would slow down to the point of compiling programs at the 
speed of a standard IBM PC,... with floppies!

That Cyber was replaced with a newer Cyber system about a year ago.  Since I
haven't done much work on it lately (I avoid it.  Almost everybody avoids it!),
I don't know how much faster it is.

By the way, something just came to mind about why your Cyber might be
so much faster than our old Cyber.  I think our Cyber had (only) two CPU's
in it.  How many does yours have?  It does seem kind of unfair, comparing
multi-CPU mainframes with single-CPU micros and saying "Look at how much faster
the mainframes are!".

Are there any other students out there who have experienced just how slow
a Cyber can be (come on Georgia Tech students, speak up!)?
