RE: interactive feature -- MIDRANGE-L

When IBM evaluate the CPW for a new processor I'm pretty sure they max-out
the memory and disk-arms for the purposes of the test.

For us mortal end-users that means we MUST take this factor into account
when we estimate the likes of this "how many users" question.

Two identical processor models can have dramatically different performance
characteristics because of memory and disk-arms.  

It is feasible that you could be worse off in an upgrade like this, though I
accept this is not probable.

Difficult to really forcast, but a 200 would handle 50 users 
pretty easily with enough memory and dasd. The 720 being quite
a bit faster processor wise, should handle 8 users standing on 
one finger. That feature is 35cpw but it's really hard to come 
up with max users and 35 cpw.... It's not one for one so it
really depends on your software and users.

Just remember this... MORE memory is a "good thing".

I am looking at adding this machine for some web related stuff.  How many
users will the above feature allow me if I decide to move from my old system
to a new one?
