Using Metadata and the RowsetCache Class
If your application uses data that is common, used by a number of users, and yet is fairly static, you may see a performance improvement by using the RowsetCache class.
PeopleTools stores application data in a database cache to increase system performance. The RowsetCache class enables you to access this memory structure, created at runtime, and shared by all users.
Note:
Non-base language users may see different performance due to language table considerations.
