This is the main development page for EclipseLink performance.

EclipseLink performance is tracked through several mechanisms.

  • Weekly regression performance unit tests.
  • Milestone third party product performance unit tests comparisons.
  • Milestone concurrency regression unit tests.
  • Milestone performance regression unit tests.
  • Public standard benchmarks such as SPECjAppServer ®.
