cpu usage

Hello!
My devkit arrived yesterday and I have downloaded latest SDK and examples. When I start Leap app it doesn't appears in the dock and in activity monitor I can see that it takes between 60% and 90% CPU usage. Examples work fine but it just does not seams to be right.
Can someone please help?
Thank you in advance!

A Macbook Pro with a Core i7 can go up to 800% CPU since they measure CPU % in terms of number of hyperthreaded cores.

Try to set "Low Resource" checkbox on tab "Tracking" in Leap settings - it should reduce CPU usage.

P.S: mine CPU usage is about 5-10%, with option above - 5-7% (AMD Phenom II X4 955 @ 3.2GHz)

I haven't had time to completely debug but from what I can tell there is a jump in network activity when the leap device initializes. This seems to be tied to the cpu usage as well. From the logs I'm guessing that the device is utilizing a websocket server to handle serializing device information to clients. I'm wondering if there is a performance bottleneck somewhere on that side. Right now it's speculative, I haven't had time to look into it further with any tooling yet.

I'm running a macbook pro as well. My only other concern was whether the server was being created utilizing the NAT address or localhost. I notice on my mac a slight difference on the roundtrip speed. For a couple of packets it wouldn't make a difference but given the amount of information being sent it might be an opportunity to speed things up slightly.

Hi Jonathan,

One thing you can try to rule out the websocket theory is to set "websockets_enabled": false in the config.json file and see how that changes your CPU usage.

What are the specifications of your computer?

Agree, I find the Leap Motion a little resource hungry.
The user experience will need to warrant this. (wow factor)
My PC is running a Core Duo 3.06GHz 4G RAM Win7.

I'm also on a MacBook Pro 2007 model running a Core 2 Duo 2.4GHz and with 0.7.4 SDK.

Seeing between 50 and 60% CPU load for me too which is rather high. Then again there's a lot of computation running I guess!

Same problem here. I'm using an Macbook Pro i7 2.4Ghz and Leap uses ~60% even without any application opened (just the leap.app of course).

I also have about 40% cpu usage on my MBP i7 with 2.6GHz, even though there is no app using the SDK.

Maybe it would be smart to only enable tracking only when there is an app / webapp using the device / sdk?

On a macbook pro, core i7, 2011 model, 4 gig RAM, I'm getting between 50-70% showing in top. In low resource mode, this drops to about 30%. Fan immediately turns on the minute I plug in the Leap, regardless of resource mode, which is a little disconcerting. Most recent SDK, etc. Hardware version 06.5

FWIW, I've got a MacBook Pro 2011 model, core i7, with 4 gig of RAM

Lol, my pc gets nowhere near that... But from seeing posts previously that sounds about right.

Core 2 Duo or Core i3/i5/i7?

Core 2 Duo, it is an older machine.

@alexander I've tried "Low Resources" mode and it reduces usage on about 40% which is still very high.
I asume something is not optimized right in this version of SDK and device because It can't be recalibrated yet... let's hope SDK 0.7.4 will fix that.

I have an i5, 4GB RAM 2010 Lenovo Ideapad and it takes 30-50% max. My brother has a sony i5 with 8GB RAM that has a similar problem as you are facing, so my answer is there is something wrong with the drivers and there are performance issues with your laptop, its not necessarily tied to Leap.
