There are following performance regressions in build 8.0-controls-scrum-h57 (comparing to h55):
Win7-High:
 Controls.ListView-Keyboard: -6% (-18.25)
 Controls.ListView-Rotate: -23% (-72.85)
 Controls.TableView-MoveRows: -24% (-19.79)
 Controls.TableView-Sort: -24% (-17.06)


The similar regressions on MacOS at least for Controls.ListView-Rotate benchmark.


The regressions first appeared in 8.0-controls-scrum-h57 and are against build
8.0-controls-scrum-h55. There is no build 8.0-controls-scrum-h56 available.
8.0-controls-scrum-h57 contains a lot of changes, so it is hard to tell which one caused the regression.
The full list of changes could be found here:

I can easy reproduce Controls.ListView-Rotate on windows7-high machine (didn't try others).
JPA analysis shows that the time spent in updateBounds and doLayoutPass has been significantly increased:

 javafx.scene.Node.updateBounds(): 0.006 => 0.139 secs
 javafx.scene.Scene.doLayoutPass(): 0.018 => 2.103 secs

The total experiment execution time was 20 secs.


Steps to run Controls.ListView-Rotate benchmark:
> cd JFX_WS/tests/performance/Controls/
> ant
> java -Djavafx.animation.fullspeed=true
       -cp "JFX_HOME/rt/lib/jfxrt.jar;./dist/Controls.jar;../FXBenchmark/dist/FXBenchmark.jar;../../../import/benchmarks-2.1.1/benchmarks-2.1.1.jar"
       jrockit.bm.Main controls.bm.ListViewBenchmark -i 1 -wt 0 -tr 60 -cells 500 -mode rotate -keysPerInjection 250


Note, you need substitute real path for JavaFX (JFX_WS, JFX_HOME variables).
