How to calculate Large BPM deployment of 2000 BPM servers ?

Basically one at every store 2 where I will run 3 end user experience scripts about 30 txns.

It’s simple : Num of BPMs * Number of transaction per BPM / run schedule in seconds

In our case: 2000 * 30 / 900 (15 min scheduler) = 66 EPS and BPM can monitor that easily.
