Re: JavaFX Application Heat up MacBook Pro

2016-03-28 Thread Tai Hu 
I finally pinpoint the problem with my application. The culprit is 
ProgressIndicator with undetermined state. There are couple places in my 
application I used a stack pane to hide a ProgressIndicator at back. Then when 
I run some task in background thread, I will bring that progress indicator to 
the front. It seems that those progress indicators are running in the 
background even though they are not visible at all. On a MacBook Pro 13 inch, 
even I leave the application idle, it took 20-25% CPU constantly. After removed 
all those progress indicator, on the same laptop, idle application only takes 
less than 1% of CPU.

Thanks all for your help.

 There is a known issue, where JavaFX (and AWT/Swing) trigger activation
 of
 the discreet GPU.  I believe for FX the issue has been resolved in the
 latest version, but the equivalent AWT fix hasn't made it to a released

BTW, I did a 15 min run of Ensemble8 testing a series of programs on my

Can you provide the steps on how you heated up your MBP running 
Ensemble8? Did you have other programs running?

Re: JavaFX Application Heat up MacBook Pro

2016-03-28 Thread Tai Hu 
My MacBook Pro is a i5 dual core with 16GB of memory. The minimal application 
that exhibits the issue is just a simple window with web view and I used D3JS 
draw a simple graph (only 5-6 nodes). Then just let application sit idle there 
without doing anything. The CPU will heat up quickly. I put the application in 
VisualVM, other than JavaFX application thread, the next thread is taking up 
CPU time is QuantumRender. But my application is just sitting idle, no 
animation or any user activities.

Re: JavaFX Application Heat up MacBook Pro

2016-03-28 Thread Scott Palmer 
This must be something else then.  How many cores are on the that MacBook? I’m 
thinking maybe there are four cores and 25% CPU could indicate that there is 
one thread stuck in a busy loop.  That could explain the heat.

Do you have any animations running?  A static application just sitting there 
shouldn’t have noticeable CPU usage. I have tons of stuff running now, not 
JavaFX though, and CPU usage is around 2%.
What is the minimal application that exhibits the issue?

Thanks for the info. What entry should I put into info.plist?

Thanks

Yes, 8u77 has the FX fix for this issue:

https://bugs.openjdk.java.net/browse/JDK-8132775

However, due to the way Apple chose to enable this, you will need to 
package your application with the appropriate entry in the Info.plist file.


The equivalent AWT fix -- 
https://bugs.openjdk.java.net/browse/JDK-8041900 -- is fixed in 8u92 
which is scheduled to be released next month.

There is a known issue, where JavaFX (and AWT/Swing) trigger activation of
the discreet GPU.  I believe for FX the issue has been resolved in the
latest version, but the equivalent AWT fix hasn't made it to a released
version yet.

What version of JavaFX are you running?
There is a known issue, where JavaFX (and AWT/Swing) trigger activation of the 
discreet GPU.  I believe for FX the issue has been resolved in the latest 
version, but the equivalent AWT fix hasn't made it to a released version yet.
