Sun's recently published SPECjbb_2005 numbers on Linux, Windows and Solaris on their Opteron system, and the Linux result is the lowest of the three by far:
Linux: http://www.spec.org/jbb2005/results/res2006q1/jbb2005-20060117-00062.html Solaris: http://www.spec.org/jbb2005/results/res2006q1/jbb2005-20060117-00063.html Windows: http://www.spec.org/jbb2005/results/res2006q1/jbb2005-20060117-00064.html
It's not evident if Sun spent any time analyzing and tuning the Linux result. While the majority of the tuning opportunities for SPECjbb_2005 are likely to be in the JVM itself, I was wondering (given the large spread between the OS's) if there were other typical opportunities to tune the Linux kernel for JVM performance and SPECjbb_2005.
There are some other results showing excellent scalability with SPECjbb_2005 on Linux/Itanium (such as SGI's: http://www.spec.org/jbb2005/results/res2006q2/ ), but it's not clear if there are other opportunities for tuning unique to Linux on Opteron, or Linux in general that should be explored
