Defects Identified in SPECjbb®2013

December 9, 2014 - SPEC has identified a defect in its SPECjbb®2013 benchmark suite. SPEC has suspended sales of the benchmark software and is no longer accepting new submissions of SPECjbb®2013 results for publication on SPEC's website. Current SPECjbb®2013 licensees will receive a free copy of the SPECjbb®2015 version of the benchmark.

SPEC is advising SPECjbb®2013 licensees and users of the SPECjbb®2013 metrics that the recently discovered defect impacts the comparability of results. This defect can significantly impact the amount of work done during the measurement period, resulting in an inflated SPECjbb®2013 metric. SPEC recommends that users not utilize these results for system comparisons without a full understanding of the impact of these defects on each benchmark result.

Additional information is available here.

The SPECjbb®2013 benchmark has been developed from the ground up to measure performance based on the latest Java application features. It is relevant to all audiences who are interested in Java server performance, including JVM vendors, hardware developers, Java application developers, researchers and members of the academic community.

Benchmark architecture diagram

New features include:

  • A usage model based on a world-wide supermarket company with an IT infrastructure that handles a mix of point-of-sale requests, online purchases and data-mining operations.
  • Both a pure throughput metric and a metric that measures critical throughput under service level agreements (SLAs) specifying response times ranging from 10ms to 500ms.
  • Support for multiple run configurations, enabling users to analyze and overcome bottlenecks at multiple layers of the system stack, including hardware, OS, JVM and application layers.
  • Exercising new Java 7 features and other important performance elements, including the latest data formats (XML), communication using compression, and messaging with security.
  • Support for virtualization and cloud environments.
