SPECjvm® 2008

The SPECjvm® 2008 benchmark is a suite for measuring the performance of a Java Runtime Environment (JRE). It contains several real-life applications and benchmarks focusing on core java functionality. It is SPEC's first Java Virtual Machine benchmark which 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.

This is the first freely available SPEC/OSG Java benchmark. By downloading it, you acknowledge that you have read, understand, and agree to abide by the terms of the SPEC General License Agreement.

The SPECjvm 2008 benchmark 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.

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.
