The reason Oracle is slower is you subscribe to the myth Oracle is Sqlserver sold by a different vendor. It is not. The architecture is completely different.
If you *ported* the sqlserver application *directly* without change to sqlserver, yes, you will have a non-performant applicationi. Sadly, there are complete armies of Oracle DBAs who do nothing but to resolve the errors made by people like you. I would buy any book on Oracle architecture or development written by Tom Kyte and he will explain you why you are wrong. He will also provide you with the tools to find out where you are wrong. Furthermore the Oracle Concepts Manual, online at http://tahiti.oracle.com, is a mandatory read. Likely, being brainwashed by the Evil Empire, aka Microsoft, you didn't read anything.

There is no such thing as a database independent app, and there will never be.
