This will be improved at 9.1.1 that will be available next month.
For now, you can open a Support Ticket and request the files to test at your TEST environment if you had it:
distsrv_9.1TF.zip
hub_9.10_TF.zip
robot_update_9.1TF.zip
As as workaround, you can try to downgrade the HUB/controller version from primary hub from 9.1 to 7.97 and probably will help on IM/AC performance.

Subject: IM/AC GUIs are very slow after upgrade from 9.0.2 to 9.1.0
Had a fresh new 9.0.2 install with only Primary hub and UMP, it was working fine. Then ran SP1 on top on both. I notice the IM/AC response time is very slow after the SP was applied. Does anyone has any experience with SP1?
