Occational Stutter during video playback - OSMC, RPi2

Help and Support
1

Seeing an occational stutter while the video playback - movies running directly from the HDD. Not sure what the exact issue is, but I do not have a lot of processes running in the background.

Below is the output of the top command (only the first few lines).

Start by disabling deluge (and any other processes) and see if the problem stops.
Once you’ve identified what causes the issue you can think about whether there are ways of making it work (e.g. lowering priority, limiting download rate, scheduling it at night), but you need to determine what causes the issue first.

You really shouldn’t install superrepo. It adds thousands of (mostly broken) repos that kill performance by checking for update and fill the log with errors. E.g.

            <name>SuperRepo</name>

Ok. I have tried removing the superrepo by going to the addon and uninstall. Also killed the deulge process. Will check and see if that makes a difference.
Quick question though - I’m under an impression that Pi2 has a separate GPU for video, if thats the case, ideally, will this make a difference?

The GPU handles video decode. The arm still handles file/network access, demuxing, audio decode, subs, GUI etc.
It could be that the stutter occues when deluge (or some other process) is thrashing the disk.

I have noticed something like this too but can’t pinpoint. Began happening after an update/upgrade on Wednesday from what I can tell.

It’s like a very, extremely brief pause. Seems to be isolated to the Pi2 as the PiB is up to date as well.

Unfortunately I don’t have much time to get logs etc.

EDIT: It does not happen when streaming online content just files from the network attached storage.

Thanks, what is the general FPS that I should be getting.
