High Boot Time

Hey everyone, I need some help here, I couldn't reduce boot time any further although I've disabled every unnecessasry service and lowered boot time significantly but can it go any lower than this. I'm attaching outputs below

A 20 second boot time on a 5400rpm HDD is very, very good. Be happy.


At this point, you would want to do a btrfs balancing, compile a custom kernel (for me, tkg-pds is pretty fast) and replace systemd with runit/s6, lol :sweat_smile:

I thought of that but i'm way too impatient to do something like that. still thnx for replying
