The point I was making is that you can always double the number of
transactions (and double the batch) on your mainframe. You would buy some

And there will be both fixed costs and variable costs to any computing
platform. Mainframes are generally characterized as having moderate fixed
costs and low variable costs. Other systems often have lower fixed costs
(individually -- collectively they can very easily be higher) and

For example, let's suppose you double the number of CICS transactions (and

double? Well, your chargebacks would if you used a single number like

of new work can be fit in that 10%)

Hello IBM-Main'ers,
I'm looking for some information on how to calculate the cost for using CPU.
Our new performance management team is trying to come up with a calculation
that can be used for multiple platforms. Those include zSeries, Unisys,
pSeries, HP9000, and intel. Since I'm not

Hello IBM-Main'ers,
I'm looking for some information on how to calculate the cost
it. Some might even argue
that there are tangible costs of -not- using the CPU.
