SPECjvm2008 on Sun Blade X6270 World record result

Tuesday Apr 14, 2009

The Sun Blade X6270 server demonstrates Sun's position of leadership in Java based computing by publishing world record results for the SPECjvm2008 benchmark. The Sun Blade X6270 server delivered a result of 317.13 SPECjvm2008 Base ops/m using the Sun Java JDK 1.6.0_14 Performance Release with the OpenSolaris 2008.11 Operating System.

Benchmark Description

SPECjvm2008 (Java Virtual Machine Benchmark) is a benchmark suite for measuring the performance of a Java Runtime Environment (JRE), containing several real life applications and benchmarks focusing on core java functionality. The suite focuses on the performance of the JRE executing a single application; it reflects the performance of the hardware processor and memory subsystem, but has low dependence on file I/O and includes no network I/O across machines. The SPECjvm2008 workload mimics a variety of common general purpose application computations. These characteristics reflect the intent that this benchmark will be applicable to measuring basic Java performance on a wide variety of both client and server systems.

SPEC also finds user experience of Java important, and the suite therefore includes startup benchmarks and has a required run category called base, which must be run without any tuning of the JVM to improve the out of the box performance.

SPECjvm2008 benchmark highlights:

  • Leverages real life applications (like derby, sunflow, and javac) and area-focused benchmarks (like xml, serialization, crypto, and scimark).
  • Also measures the performance of the operating system and hardware in the context of executing the JRE.

Given a check of the published results on www.spec.org shows that Sun are the only ones publishing results on SPECjvm2008, it seems a rather dubious distinction claiming world leadership :)
