can you please provide some more information? with such an incomplete bug
report its really hard to try to fix anything,

Which datasoul version are you using? Which architecture, java version,
desktop environment?

I use it here in ubuntu 12.04 with normal cpu usage,..

BTW, it would be helpful to have also:

1. Output of 'top' showing which other processes are also using the cpu.

2. Output of a SIGQUIT (in a terminal, find datasoul's PID using 'ps ax'
then use 'kill -QUIT <datasoul_pid>). It should give us the stack trace
for all java threads.

3. Attach VisualVM [1] to datasoul, monitore the threads for a while and
report which thread is currently using the cpu.

Thanks

Hi,

Thank you very much.

Sorry, I forgot something about the kill -QUIT thing. Please start datasoul
from the terminal. When you send the QUIT signal the output will appear in
the terminal where you started datasoul.

I created a screenshot about the VisualVM:
https://docs.google.com/file/d/0B1Uhswwg9w15UVhUeW0tRFU0M1U/edit

First select datasoul's process in the tree in the right, then select
the 'Threads' tab, wait until it fills the screen, take a screenshot and
send here.

It would be good if you use the same datasoul session for both, so we can
correlate the kill -QUIT and the VisualVM outputs.


Do you do anything special or it just starts using cpu after start?

Thanks

Ah, if you could, please send also the output of VisualVM in Profiler tab,
then click on CPU icon.

I'm trying to reproduce the problem here without success, yet.

Are you using Live or Video as background?

In VisualVM, if you wait some time do you get other entries beside
LivePanel and TimerManager?

Hum... this give us a good hint.

If you disable it (use static background) the cpu usage goes to normal
levels?

When you enable the output, does the video run smoothly? How are the cpu
usage then?

Can you provide us some information about the video (codec, resolution,
size, etc)?
