UIM performance is very slow after upgrade to DX UIM 20.4 CU6. The page takes too much time to load. Groups (group members) do not populate within a reasonable time or no groups show at all. This may also affect Inventory display.

nas Best Practices, Tips and Techniques (for Large Environments)
Please do the following for EACH UMP / Operator Console instance:
1. Via Raw Configure mode, under startup->options, please add an additional 2GB to each WASP instances' current java min/max settings...for example:
2. Deactivate the wasp
3. Wait for the port and PID to diappear
4. Activate wasp
You can also review the wasp log at loglevel 5 to see how much memory is still available and if its close the maximum memory already configured/allocated add 1-2 GB more to the java heap settings.
