ArcGIS Server 10.5 Windows
This question has been beat to death, but like others have said, documentation is hard to follow and described differently in places. I understand all of the concepts and what is done, so I am hoping this is a simple question.
For a service, in some cases max instances can be set to n + 1 (n number of cores).
Does this mean for a 3 machine site with 4 cores on each machine the number is 12 + 1, or 4 + 1?
E.g. 4 cores each of three machines
4 x 3 + 1 = 13 max instances or 4 + 1 = 5 max instances.
