The performance problem of server side PreparedStatement?

I test the PreparedStatement performance comparing with createStaement based MySQL server 4.1.7 and Connector/J 3.1.5. And I find the PreparedStatement will have better performance only when I use the same PreparedStatement object before closing it. If I close it and re-create it by invoking connection.preparedStatement() again with the same SQL string, it will get worse performance than directlly using createStatement().
How ever, I think this is a problem since the Connection should cache the PreparedStatement object for re-using purpose. Otherwise, it will increasing the developer effort for caching these PreparedStatement objects.
