We need to know the I/O recommend rate for the CA UIM Database for a large-scale environment.
Release : 9.0.2
At this time, there is no documented I/O Rate for Database for UIM 9.0.2 (or even for the newer version).
The rate really varies depending on the environment capacity and the traffic between the Database and the UIM server.
Theoretically, the data_engine can push approximately 100,000 inserts per second maximum.
For the database size recommendation for UIM 9.0.2, check this old discussion with recommendation.
