Performance

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 ®.

Tests
