Tuning ArcGIS Server instances
We are running ArcGIS Server 10.6.1 and are having some performance issues. We are experiencing heavy memory consumption that I'm thinking is attributable to a high number of ArcGIS SOCs running. I am trying to fine tune the services and would like some help in really understanding what happens after I publish a service.
When I connect to the ArcGIS Server in Catalog and view the services, there are two columns referring to the number of instances for a particular service: "Instances Running", and "Instances in Use".
1) What is the difference between these two columns?
2) Which column is related to the ArcGIS SOC created on the server?
3) Even if I set the number of minimum instances running to 0 there occasionally is still "1 Instances Running" but "0 Instances in Use" why is that?
4) In my simplistic nature, I assume the more heavily a service is being requested the more instances I need to have available?
5) In a scenario where a user has a web map open but the layer is turned off, is that layer still requesting an instance or not?
Any help in deepening my understanding of this process to help my end users and adjust for performance gains would be greatly appreciated
Cheers,
Heath
