We have an add-in for ArcGIS Pro that we have updated to utilize referenced feature services via ArcGIS Enterprise. In our testing we have found that when we utilize a service from an Enterprise deployment in AWS we get much worse performance when using dedicated instances for the service (about 40% slower). This is not affected hardly at all by changing the cloud machine hardware as well as the settings for min and max dedicated instances. However, when testing this on a locally deployed Enterprise environment we are seeing a slight improvement when using dedicated services. So our question is what would be causing the cloud deployment/environment to cause such a large performance hit when using the dedicated instance type.
I attached a screenshot of the two instance types we tested with.
