To simplify querying the logs (for making performance improvements) we started consolidating our per-app Application Insights resources into combined ones some time ago. The biggest one now tracks 90+ app services running .NET.

It looks like the Azure Portal has some trouble working with that many apps in a single Application Insights resource, because I've noticed trouble with rendering some pages, especially the "Roles" tab on the "Performance" page. Both Firefox and Chrome often show warnings about slow scripts when opening that tab or changing the time range ("A web page is slowing down your browser." and "Page Unresponsive")


Since this doesn't happen on App Insights resources with only a few resources there must be some number at which this starts occurring. So:
1) What is the max number of resources that can be tracked in a single Application Insights resource?
2) Can the Azure Portal or Application Insights teams maybe fix this problem?
