Hi all, Thanks for the responses. I'll check that the Linux guys are using the latest kernel just to be sure.
Mark, are you suggesting that the Oracle team should have some actual data to back up their claims? Not just a bloke with a stopwatch and an uneasy feeling?! ;-) But yes, I have already asked them to raise this with SUSE support in the hope that they'll get some real data together. Thanks all.

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.
