EclipseLink/Development/Performance

This is the main development page for EclipseLink performance.

EclipseLink performance is tracked through several mechanisms.

• Milestone concurrency regression unit tests.
• Milestone performance regression unit tests.
• Public standard benchmarks such as SPECjAppServer ®.

Tests

Component	Test	Description
