Thanks for the insights!
I have a DS1019+ … so I have the feeling it goes a bit better but as per your note did not delete the logs.
Talking about logs: Do you keep them in the docker / so not write to file so they delete when an update comes out? Or is it better to output them? I’m talking performance, not storage / and that it’s better to keep them so you can check later 
And something else I’ve noticed:
RAM shows in docker 5.23 GB where as RAM usage shows 956 MB… also in my resource manager it doesnt show the high number:
Any idea why that is?
