Oh, and I just realized, that I have two custom settings in my /etc/rc.local - guess, I configured that when I installed that machine years ago. Sorry, that I haven't mentioned that earlier. echo 0 > /sys/block/nvme0n1/queue/read_ahead_kb echo never > /sys/kernel/mm/transparent_hugepage/defrag That setting is probably not quite standard, but I assume there are some database server setups out there, that set RA=0 as well.
