It's been fun following Intel's launch of the 2-socket Nehalem chip. This is the first time that I can remember having SPECjbb2005 results available on launch day using each of the 'big 3' JVMs.
Kudos to Oracle JRockit for having the first Nehalem based SPECjbb2005 results available on www.spec.org using a new P28.0.0. JVM.
The Sun HotSpot results using a new Java 6 Update 14 Performance Release are referenced here.
The IBM J9 result is 8-10% faster than the JRockit and HotSpot results .... not surprisingly Intel went with the J9 result on their Nehalem benchmark page.
