Why traffic manager does not distribute traffic evenly across all endpoints?

Question

I have a traffic manager in Azure, with routing method as "performance".

Currently it has two endpoints, westus-a and eastus-a, each endpoints serves 1k/min request. An hour ago I added another endpoint westus-b to this traffic manager. After waiting for ah hour later, the traffic to westus-a only decreased a little portion, and westus-b only serves 200/min requests.

According to this document:

If your profile contains multiple endpoints in the same Azure region, then Traffic Manager distributes traffic evenly across the available endpoints in that region.

If this is the case, the westus-a and westus-b should both serve around 500/min request.

Also according to another document, the "performance" routing method relies on the internet latency table to choose the least endpoints.

Both westus-a and westus-b are deployed in West US region, there should not be so much difference in terms of latency among these two endpoints.

Hi Shunei, Welcome to MS Q&A

Use Nested Traffic Manager Profiles: This helps distribute traffic evenly across the available endpoints in the particular region.

Please check this doc for https://learn.microsoft.com/en-us/azure/traffic-manager/traffic-manager-nested-profiles
