There was a significant performance bug (to the point of non-responsiveness) initially where it got itself into a swap fest. Do you have a current kernel?

IBM submits quite a few performance enhancing feature requests for each service pack we produce. I would be surprised if there was a significant performance degradation in SP3, particularly with Oracle. All of the IBM presentations I've seen say that in general, things are better. Have you opened a support request with your support provider about this? If you have not yet, they're going to want real data when you do open one. Hand waving/wringing from the Oracle support team isn't going to be sufficient.
