wiimote cpu load [closed]
Hi all!
I am experiencing a weird behavior in wiimote_node. When I launch it and subscribe to the /joy topic, the CPU load of the node goes up to 140%! I run the node in an Intel Core2 Duo, where each processor is 1.8 GHz. It seems that those CPU loads are not justified, but I saw in the code that the publishing rate is 100 Hz. Although I changed that frequency to 10 Hz the node keeps on consuming the same CPU. Does anybody have a clue about it?
Thanks in advance!

That seems really weird. How are you measuring the CPU usage of the node (e.g. top)? Does it use the same amount when you aren't subscribed to /joy? What about subscribing to one of the other topics output by the node (/imu for example)?

I measure the CPU usage with top. The usage doesn't change with subscriptions. Even without subscriptions, usage is always around 140%. I did the same test in my laptop (Intel Core i5) with a new diamondback installation and I get a usage of 113%

I'm in china currently, I will look into this problem when I get back and see if I can reproduce this problem. I filed a ticket here for myself: https://code.ros.org/trac/ros-pkg/ticket/4948

I see the CPU load and am on it!

I also tested the wiimote node on a Atom-based FitPC2 and noticed it maxed out the CPU completely. Good to see it adressed :)
