XMLWordPrintable

      There is 68% regression in SpiralText in hw pipeline appeared in promoted build 8.0-h96-b68.
      Here are the results on Win7-High-Range machine:
       8.0-h90-b67: 38.34 fps
       8.0-h96-b68: 12.32 fps, -68% (-26.02 fps)


      The regression is caused by fixed
      RT-23704 "Use DirectX 9Ex mechanism to avoid calling cv.save()"

      Running the test with disabled D3D9Ex (-Dprism.disableD3D9Ex=true) results in no performance regression.

      Steps to run SpiralText:
      > cd JFX_WS/tests/performance/SpiralText/
      > ant
      > java -cp "JFX_HOME/rt/lib/jfxrt.jar;./dist/SpiralText.jar;../FXBenchmark/dist/FXBenchmark.jar;../../../import/benchmarks-2.1.1/benchmarks-2.1.1.jar"
