Excessive CPU usage on Raspberry Pi #36

Closed GorkaMM closed 5 years ago

GorkaMM commented 5 years ago

Homebridge increased CPU usage significantly after installing this plugin.

Expected Behavior

CPU usage should stay as it was before installing the plugin (less than 10%), or increase it only slightly.

Current Behavior

Homebridge running on Raspberry Pi Zero WH with Raspbian Stretch has a ~60% CPU consumption on average.

Steps to Reproduce (for bugs)

Run Homebridge on Raspberry Pi Zero WH with Raspbian Stretch and Node v10.6.0.

Weird, these are my load averages: load average: 0.05, 0.09, 0.08. Can you see anything in the logs that look odd? Could you be running with debug-mode enabled? That would cause a lot of output.

I have done some cleaning up and it seems to be around ~11% on average. I will keep an eye on it and let you know. We can keep this issue open or close it, whatever you prefer.

Thanks a lot for the fast response.

That's more reasonable. Please keep an eye on it. It got me a bit worried that this was something introduced by the @abandonware/noble when running Node 10. I'm running the current master but on Node 8.15 and I can see no indication of this.

Let's keep the issue open for now.

After some time looking into it, It seems to be caused by another plugin. I'm closing this for now. Thank for being attentive!
