RE: IDS Performance on RS6000

I will say I have not had issues with the RS6000's at my company. I think we have somewhere around 100 instances of IDS (most of them small I admit) and have had lots of success as far as both stability and performance. I have only worked on one Sun box and it was fairly stable as well. I would be interested in seeing an E10000 benchmarked against an S80. Anybody got some free cash for a benchark?
