You are half-way there, Evan, with your 50 users :-)
 
        The challenge to Oracle still remains:  100 users.

"Performance characteristics"?  Is that a new euphemism or what?  :-)

Ahem.  That's the whole point of this little discussion:
 
        MPE Users Kick Butt!

Thanks, Evan.  Your last point is worth repeating, just in case some people
missed it:
 
        Luckily we'll only have 4 concurrent users for that
        application -- I figure a 12-way T520 with 3.75GB
        ought to be able to handle the load...   ;-)
 
 
 
I rest mi case.
