Hi Wayne:

You're likely to get answers all over the board on this one, but perhaps
that is exactly what you want.

Other than some obvious restraints, like virtual memory,
network bandwidth, CPU cycles, etc., I have never heard of an
IDMS system that could not support the maximum concurrent
number of users (albeit I had a lot of fun during the Cullinet
years doing performance and tuning consulting to achieve
exactly that result ;-}} ).

That said, I suspect you may be asking about life in the 'new
world', with web services, etc.

I have personally simulated 10K users hitting an ASP page that
connected/retrieved minimum data from an IDMS database. I
don't have all of the details anymore, but the overall response
was about 1.17 seconds running the simulation for about 15
minutes. This was done on CA iron in
2003/2004 on a R14.1 CV.

Of course, it was just a simulation, but it illustrates that
you can push a rather large load through a CV if you have
enough back-end resources.
Again, just my 2cents...your results WILL vary...

Does anyone have an idea of the concurrent number of users IDMS
can handle?
