There seams to be a maximum parallel tile requests when using a wmts service in ArcGIS pro, similar to how web browsers throttle the number of requests to a single domain.

How to reproduce:

add a wmts service to your map in ArcGIS pro, zoom in and look at the web request logs

What I expect:

In arcgis 9.x and 10.x the server receives all the tile requests at once and is able to fulfill all of them simultaneously

What actually happens:

I see some requests, and then after they finish I see more coming in making the the layer take much longer to load

Idea:

remove the limit and make sure ArcGIS Pro wmts performance isn't regressed compared to 10.x
