 ```
 *NOTE:* The `batchInsert` function will still create multiple `INSERT` statements when interacting with your database. You most likely want to couple this with the `rewriteBatchedInserts=true` (or `rewriteBatchedStatements=true`) option of your relevant JDBC driver, which will convert those into a single bulkInsert.
 You can find the documentation for this option for MySQL [here](https://dev.mysql.com/doc/connector-j/5.1/en/connector-j-reference-configuration-properties.html) and PostgreSQL [here](https://jdbc.postgresql.org/documentation/94/connect.html).
+
+If you don't need to get the newly generated values (example: auto incremented ID), set the `shouldReturnGeneratedValues` parameter to false, this increases the performance of batch inserts by batching them in chunks, instead of always waiting for the database to synchronize the newly inserted object state.
+
+If you want to check if the `rewriteBatchedInserts` + `batchInsert` is working correctly, check how to enable JDBC logging for your driver because Exposed will always show the non-rewritten multiple inserts. You can find the documentation for how to enable logging in PostgreSQL [here](https://jdbc.postgresql.org/documentation/head/logging.html).

 ## Insert From Select
 If you want to use `INSERT INTO ... SELECT ` SQL clause try Exposed analog `Table.insert(Query)`.
