This benchmark suite is intended as a tool for Java benchmarking by the programming language, memory management and computer architecture communities. It consists of a set of open source, real world applications with non-trivial memory loads.

The initial release of the suite was the culmination of over five years work at eight institutions, as part of the DaCapo research project, which was funded by a National Science Foundation ITR Grant, CCR-0085792. A further three years of development went into the 2009 release. The third release took a further fourteen years. That work was been funded by the ANU, the Australian Research Council and a generous donation from Intel. Since then, development has continued at ANU with support from Oracle and Google.

Our suite evolves to maintain its relevance. It is therefore essential that you cite the version number associated with the release in any use of the benchmark, and as a courtesy to the developers, we ask that you please cite the paper from OOPSLA 2006 describing the suite:

• November 30, 2024 We are very pleased to announce a maintenance release, dacapo-23.11-MR1-chopin.

  The maintenance release includes:

  • Standalone launcher jars in support of AOT systems such as Graal NativeImage.
  • New metrics for request-based workloads.
  • Many additions to the nominal statistics, plus comprehensive statistics added to the release folder, dacapo-23.11-MR1-chopin/stats.

  As a maintenance release, we avoid modifying workloads wherever possible. The selection of benchmarks and their versions are unchanged. The following bug fixes were made to benchmarks:

  • Incorportate upstream h2 bug h2database/h2database#4125, affecting h2, spring, tradebeans, and tradesoap (#309).
  • Populate database in prepare phase for tradebeans and tradesoap (#304).
  • Disable logging for YCSB client in cassandra (#272).
  • Reorder key loop nest for lusearch (#264).
  • Fix a race condition in sunflow (#258).

  See the RELEASE NOTES for more information.

• November 8, 2023 14 years since our last major release, we are very pleased to announce the release of dacapo-23.11-chopin.

  The release includes:

  • New latency metrics, capturing user-experienced tail latencies for eight request-based workloads and jme, a rendering workload.
  • Integrated benchmark characterization metrics which capture defining attributes of each workload.
  • Eight new benchmarks: biojava, cassandra, graphchi, h2o, jme, kafka, spring and zxing.
  • A complete overhaul of the trade benchmarks, replacing geronimo with wildfly.
  • Full updates of all existing benchmarks, bringing them up to date with latest stable versions.
