[jira] [Created] (OPENMEETINGS-926) Screen sharing webapp CPU usage.

SebastianWagner created OPENMEETINGS-926:
--------------------------------------------

             Summary: Screen sharing webapp CPU usage.
                 Key: OPENMEETINGS-926
                 URL: https://issues.apache.org/jira/browse/OPENMEETINGS-926
             Project: Openmeetings
          Issue Type: Bug
            Reporter: SebastianWagner


I understood there are a couple of improvements for the screen-sharing. As demanded by many people. However one of the challenges was always the CPU usage. If you scan the screen for too many updates and calculate the needed frames, the screen-sharing takes 100% of your CPU.

Especially for us this is a problem. Unfortunately the Flash Plugin sharing your camera already takes 20% of the CPU. If you choose a higher resolution even 40-50%.

On my system (Mac OSx, 4GB Ram, Dual Core 2.4GHz, Java7, default screen sharing settings) the cpu immediately jumps to 120%. I can make a 1 minute demo video but for a real conference I can't use that tool.

I would like to verify: What is the CPU usage on your machines?
Do we have some kind of benchmark for different machines?
