exiftool processes: 100% CPU load on RPi2 #1437

Open pjotrek-b opened 6 years ago

pjotrek-b commented 6 years ago

When I browse e.g. by Genre, the CPU load on my Raspberry Pi 2 goes to 100% - staying there for a veeeeeery long time. Can be easily up to 10mins (or longer). This causes the web-UI to become completely unresponsive :cry:

This is a music artist's recording studio collection, so it's not that small: 10221 tracks (719h30m47s playtime)

Here are the head lines of "top" when that happens:

I guess this is caused by the web-UI loading the cover images. Is there any way to disable this, or maybe configure a "nice value" for the exiftool processes?

OS & version is: volumio-2.348-2017-12-22-pi.img

Disable embedded albumart on Playback options

Thanks! :smile: Will do that.
