I am continuously asked by management how many simultaneous users per 4-core ArcGIS Enterprise 10.5 license. Conversations with colleagues in the public and private sector put the number at around 100 - 125. What is the general consensus of those who manage an ArcGIS Enterprise system? When does performance really taper off? What causes performance to taper off?
A few more details include the following:
No advanced geoprocessing
Simple routes and Smart Editor
No in-house imagery
No additional 3rd party tools and widgets
Roughly 50 to 75 services
