SPECjbb2000 (Java Business Benchmark) [1] is SPEC's first benchmark for evaluating the performance of server-side Java. Joining the client-side SPECjvm98, SPECjbb2000 continues the SPEC tradition of giving Java users the most objective and representative benchmark for measuring a system's ability to run Java applications.

As of January 2006, SPECjbb2000 has been retired and replaced by SPECjbb2005. Results submissions are no longer being accepted and support is no longer provided.

SPECjbb2000 Benchmark Highlights

  • Emulates a 3-tier system, the most common type of server-side Java application today.
  • Business logic and object manipulation, the work of the middle tier, predominate.
  • Clients are replaced by driver threads, database storage by binary trees of objects.
  • Increasing amounts of workload are applied, providing a graphical view of scalability.
  • See the architecture schematic of the SPEC JBB2000 benchmark process.
