High CPU Usage #80

Closed capitalPSA closed 4 years ago

capitalPSA commented 4 years ago

Is there a reason behind using between 200-300% of the total CPU resources? The package is built in Release mode, the "rgb8.launch" is run, and the ueye_cam is being triggered. Yet the CPU usage is very high; is this correct behavior?

Is there a way to disable the OpenMP library use?
