Minimserver in Docker Container Keeps Writing To Disk

I am using either the Linn or the Lumin app on an iPad (I want to use OpenHome).
BubbleUPnP gets good reviews, but unfortunately is Android only.

Am I right that all your suggestions with indexing and tags still rely on browsing my library through the ‘Folders’ view?

In particular Lumin, the app with the best user interface, has fixed buttons for Songs, Albums, Artists, Composers… which are directly visible (no navigation through a hierarchy necessary). If I tap, e.g., on ‘Artists’, I see a tile for each artist, with all the songs for that artist behind the tile, regardless of folder. There is no way to narrow down by other tags (like the ones you suggested): If the same song has copies in three different folders on the server it will show up three times.

To do this in a Docker container, you need to create a file /opt/minimserver/etc/minimstart.conf in the container with the contents

javaopts = -XX:-UsePerfData

You can use a Docker terminal window to create this file. After doing this, you need to stop and restart the MinimServer container.

Since I have so many containers I ran a variety of tests:

• Create the container with or without the “--no-healthcheck” and "--log-driver none" parameters, as suggested by bubbleguuum above
• Start the container with or without the “javaopts = -XX:-UsePerfData” parameter in a minimstart.conf file, as suggested by you.
  

Of the possible four combinations, only one yielded the desired results: Adding “--no-healthcheck” and "--log-driver none" to the container creation AND starting the container with the “javaopts = -XX:-UsePerfData” line in the minimstart.conf file.

Only with both these options chosen, the NAS went to sleep after the expected time.

My command to create the container was
sudo docker run -it --no-healthcheck --log-driver none --network host --name HiRes-Stereo minimworld/minimserver:latest

Would it be possible to add these three settings (switch off healthcheck, log driver and performance data recording) to the next version of the Docker container image?

I appreciate your engagement in this discussion and helping me find a solution that works!
