------------------------------------------------
I have tested screen sharing on Windows 7 x64, CPU Intel Core Duo 2,53 GHz, RAM
4 GB.
Resolution 1280 X 1024
FPS 2 5 10 15 20 25
CPU(%) 20 30 30-40 40 40-45 45
Recording Ok Ok Fail Fail Fail Fail

> Key: OPENMEETINGS-926
> URL: https://issues.apache.org/jira/browse/OPENMEETINGS-926
> Project: Openmeetings
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: SebastianWagner
> Priority: Critical
>
> 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?
