#136

It has been suggested that I/O-schedulers may play a role in this. So here's
are my settings for 4.19.x for comparison. They deviate from yours in some
points but I really don't know whether this has any relevance. You may want to
give it a try anyway. As I've said, 4.19.x is a nice kernel here.
