> Key: OPENMEETINGS-926
> URL: https://issues.apache.org/jira/browse/OPENMEETINGS-926
> Project: Openmeetings
> Issue Type: Bug
> Components: Screen-sharing
> Affects Versions: 3.0.0
> Reporter: SebastianWagner
> Priority: Critical
> Fix For: 3.0.8, 3.1.0

>
> 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?
