Tuning is very important, sometimes it pulls off huge improvement. Because CPU means nothing without software running on it, but softwares are written by people who very possibly do not know how to utilize CPU best. Intel definitely helps its big customers(BEA, SAP) tune their major software products. It's a win-win if they can sell the "platform". Do you want a JRokit with this much performance? Good, go buy a Woody because we only can reach there with it. What you go a Woody already but needing a JVM? Well go for BEA because that's the fastest master piece so far...
