Repeatedly importing data that has not changed leads to many skipped rows and unnecessarily bounds system resources.
Ensure that each import is not importing all records every time by using the "Use Last Run Datetime" option. If you are running a JDBC import, use the last run datetime option in your import set Data Source. For a type of File import, be sure that whatever is generating your files is only adding data that is new, or has been changed.
