[Ashish Vijaywargiya-5]

Till now I am using mysql-connector-java-3.1.13-bin.jar file. - It is
working fine.
But now a days thinking to switch to the mysql jdbc connector 5.

If you are using MysqlJDBC connector 5 then any performance improvement
in it?
Please let me know your thoughts so that I will move to the mysql
connector 5.
