Our infrastructure is as follows:
Our primary hub collects QoS data using get, from an attach queue on our integration hub. The integration hub collects QoS data from the regional hubs.
Since upgrading the attach queue for QoS data on the attach queue on our integration hub has been emptying very slowly. We're not collecting any more data than we did before the upgrade, but the Primary hub but we're seeing data backing up consistently.
Before the upgrade we did not have an data queued at all, everything was being processed immediately.
Something is wrong with the upgrade to 20.3, the hubs are just not transferring data as quickly as they used to.
How do we fix this?
