Re: Processor speed

In our situation it helps when the CEO keeps pestering us 
to remove the last NT Domino application off of the NT box 
and put it on the 400 ASAP.

I have to say that I agree with you. It would seem to me that the lower end
machines do not deliver what an NT box solution appears to deliver, but when
you get to a couple of hundered users, then it's pretty difficult for an NT
box to compete. Unfortunately, the AS/400 needs to be sized correctly in the
first place, and certainly for smaller sites, the cost of an AS/400 to do
the job would (IMO) bury the AS/400 as a viable option. Running Domino on
the AS/400, especially if anything else is running, seems to require a lot
of initial grunt, far more than a comparable PC server would seem to
require - and at a far pricier premium.

Compounding the price performance issue is the difficulty of understanding
how to tune and administer Domino. My experience so far is that the Domino
Adminstrators I have encountered tend to offer "run it on an NT box" as
their advice when quizzed about scheduling, memory and resources etc.
therefore the AS/400 person is left to try and tune Domino running on the
AS/400. Not an easy task, especially as all the "old ways" are not quite
applicable.

Scalability is not really an issue when the in-house testing of Domino fails
and an NT solution appears to offer a more reponsive and robust solution and
the Domino Adminsitrator (who probably has NT at home with Domino running on
it) is quietly promoting NT.
