ORM Performance Scorecard


    • Color bar: Green cells indicate better results; Red cells indicate worse results (the most "red" value is explicitly defined in Landmark column); Yellow cells indicate average results. Color bar is continuous, so all the intermediate colors can be used.
    • Above results are produced for 1000 item sequence. Complete ORMBattle.NET Test Suite output (for 100, 1K, 5K, 10K and 30K item sequences) is here.
    • Some ORM tools were not tested for LINQ implementation - either because of impossibility to do this on our standard tests and model (Subsonic), or because of lack of tests (BLToolkit).
