After a lengthy discussion with Client Care about it taking 30+ seconds to even access the user management interface, they confirmed that such a load time is expected, and if I wanted it to improve, to add this as a feature request on the Idea Exchange...
So here I am. See details from CC chat transcript:
Me (Client): it took 30 seconds from clicking the "users" button within the admin console Me (Client): no timeout but still unacceptable Adobe CC: Matt, this is expected, if you want to see better performance on this I would suggest a feature request through the ideas exchange. Adobe CC: this is not more than the normal Adobe CC: I have tested this with 2 additional companies while we have been on the chat and the load times are around the same, between 20-30 seconds
Simple user management tasks should not take several minutes (string together waiting 30 seconds on each step) on an expensive, mature, enterprise analytics tool like SiteCatalyst.
