I have an application that was working fine in version 6,7,8 without error. After we migrate to 9.0 in our testing process look ok. Now in a real world a client that have one of the biggest demand have a complaint because a regular process that normally take like 3 minute to complete is taking hours. Any person have any idea where I have to start looking. Was working fine in previous version so I dont want to modifie anything before I check that is something that I need to do with the setup of 9.0 in order to work fine.
