1. We are exposing a service in Pega, we have to fix the requestor pool size, how do we get the number (how many requestors can be served at a time) ?

2. what are the factors and parameters we should consider to achieve this number?

3.How do we figure out the optimize number? Traffic is one of the parameters (at a min / at a sec, service goes live how many requests could be coming at a point)

 what could be the other parameters?

Thanks,
