Jdbc inserts are very slow : JDBC JAVA

This is a discussion on Jdbc inserts are very slow within the JDBC JAVA forums in Framework and Interface Programming category; hello, I'm having a performance issue with mysql. My code is performing 15000 inserts to the db. I'm using preparedStatment and addBatch and executeBatch, I've tried many batch sizes, but nothing helps. for 100 batch size it takes 35 seconds! When I make the batch size bigger, I get no performance increase. How can I make this code perform better?...
