Description Lark Fitzgerald 2008-10-16 22:01:29 UTC 
Tested using Promoted SDK/Plugin build #25
Product: javafx-1.0dev, Platform: windows-i586, Build-Number: 741, Build-ID: 2008-10-14_17-39-02 on:
Product Version: NetBeans IDE 6.5 RC1 (Build 200810151402)
Java: 1.6.0_10-rc; Java HotSpot(TM) Client VM 11.0-b14
System: Windows Vista version 6.0 running on x86; Cp1252; en_US (nb)

1. create Simulation > Flocks sample
2. deploy it

It runs but its REALLY slow.  The CPU starts spinning at 100%.  I tested this with both 1.5 and 1.6.  Its slightly 
slower on 1.5.

Can you point me to the Runtime bug?
Comment 5 Lark Fitzgerald 2008-10-22 15:13:37 UTC 
Reopening for tracking purposes. If this issue is not fixed then we must remove this sample before we release.
Comment 6 Lark Fitzgerald 2008-10-27 19:45:00 UTC 
See: http://openjfx.java.sun.com/jira/browse/RT-1682
Comment 7 kcr 2008-10-27 22:19:30 UTC 
http://openjfx.java.sun.com/jira/browse/RT-1682 was closed as a duplicate of
http://openjfx.java.sun.com/jira/browse/RT-1542. The root cause of the worst of the problem is
http://openjfx.java.sun.com/jira/browse/RT-724 : Rendering is stalled if a repeating KeyFrame action takes longer than
its specified duration.

This issue will not be addressed for JavaFX 1.0. The workaround for the stall (which causes most of the jerkiness), is
to set the "canSkip: true" flag in the KeyFrame in your sample.
Comment 8 Michal Skvor 2008-10-30 10:29:53 UTC 
Added canSkip flag.
