New SPECjbb2005 World Record - Java SE and UltraSPARC IV+

Sun has again achieved a new world record on SPECjbb2005, beating IBM's latest result by 1.5%. Take a look at the press release. This result is using the newly released J2SE 5.0._06. IBM's score: 244,361 bops, 30,545 bops/JVM Sun's score: 248,075 bops, 31,009 bops/JVM Both the IBM and Sun results are 4 instance SPECjbb2005 runs. Each result has 32 "Processors" available to Java, as determined by the Java API java.lang.Runtime.availableProcessors(). The systems are equivalent from the view of Java, each has 32 hardware threads or "virtual" CPUs. How the 32 threads are implemented on each system is different, for example take a look at the Sun Fire 6900 details. I like that IBM is actively submitting SPECjbb2005 results. Competition spurs innovation, which is a great thing for everyone, especially customers with enterprise Java server applications. It would be great to see other large system vendors step up and compete on SPECjbb2005. HP? Fujitsu? Try running with Sun J2SE 5.0_06, its rather easy. Fine print SPEC disclosure: SPECjbb2005 Sun Fire E6900 (16-way, 16 chips, 32 cores) 248,075 bops, 31,009 bops/JVM submitted for review, IBM eServer p5 570 (8 chips, 16 cores, 16-way) 244,361 bops, 30,545 bops/JVM . SPEC, SPECjbb reg tm of Standard Performance Evaluation Corporation. Results as of 11/30/05 on www.spec.org unless otherwise noted.
