1. i observed that my webbroser use about 30 % of cpu when i start a voice

2.my webbroser still use about 30 % of cpu after i closed the voice 

3. the high cpu usage end only with the end of conference and login out of
the conference 

4. my cpu usage is about 5 % when i only start my webcam without voice and
the 5 % cpu usage ended when i close my webcam

I've noticed with VOIP as well, but seems to consistent across platforms and 
with SIP
and IAX softphones.

However, more problematic seems to be desktop sharing, where CPU load on both 
Windows
(FF) and MacOS (Safaria) actually pegs near 100%. Probably need to look at 
this. For
comparison, the g2m applet runs a lot of threads but maintains about 40% and the
OpenMeetings applet runs under 50% (and both perform quite well).

Yes, Desktop sharing consumed all accessible CPU power in 0.63. This has been 
fixed for 
0.64. You can test it on devbuild.bigbluebutton.org

That's confirmed when running clients (firefox ,chromium and others) from 
another
machine ( box) or (virtual machine).to communicate with bbb server in another 
machine

i am running client and server in same box (machine) , and i still have high cpu
usage ,also my biggest problem  still point 3:

---- 3. the high cpu usage end only with the end of conference and login out of
-----the conference

I've looked into this and the cpu usage is simply due to flash doing voice 
encoding. 
With desktop sharing, the applet is doing the encoding of the desktop video so 
there is 
greater flexibility with it. With the audio there's no way for to tell flash to 
use 
less CPU to encode. So there's nothing we can do about this. The cpu usage 
remains high 
because right now there is no way to leave the voice conference once you've 
joined it, 
but that is a separate issue.
