| 2015-04-03 17:57:28 -0500 | asked a question | High CPU usage with listener/talker on RPi Hi, I am using a Raspberry Pi running Debian with Indigo distro installed on it. I was surprised verifying that the simple listener/talker pair from the tutorials was consuming about 40-55% (20-30% each node) when the talker was running at 100Hz. The only modification made on the source was on the talker side to change the frequency. I would expect much less CPU load... Has anyone found similar issues? Does anyone have any idea why this happens? Could it be an issue on ros-comm package on RPi? Any clue? Thanks in advance for your help. |
