Calculating optimal Batch Server's Maximum active queries settings

Hi,

Question: Is there a simple formula for setting up the Maximum active queries number and its single main runtime limitation before considering Application Clustering with multiple main runtime?

I usually observe Maximum active queries settings was normally set on basis of it depends.

Normally, I estimate based on: (recurring tasks set to active * fixed hours) or current unused vCPU count of Sage X3 Application Server with the runtime and multiply by 2.
