--------------------------------------------
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?
