Any clues as to why Debian takes 4 to 5 times as long? I'm hoping there is some bad configuration out of the box causing Debian 12 to be acting so slow. Anyone have any ideas where I should start looking? If I can't get to the bottom of the problem I will be staying with Linux Mint.
Try `dmesg | less` and see if anything eye-catching is in there.
Also, `journalctl` with some option like `--boot=-1` for *previous* boot logs, or for running in Mint with separate partitioning, `journalctl --directory=/path/to/debian/logs`.
Note that `journalctl -k` or `journalctl --dmesg` will show only kernel messages, like `dmesg`...
Hope this helps somehow.
One of my favourite recent discoveries are the abilities of `systemd-analyze`. `systemd-analyze blame` shows how long every step in the boot process took. It's worth looking at, but doesn't account for the fact that many of these things run in parallel. So to better understand what's causing the _real_ delays, try `systemd-analyze critical-chain`. The output is fascinating and I hope helpful ... but please keep in mind that I never got further than that so I can't tell you how to speed up the problem areas ... But the last command may at least focus your search in the `dmesg` output. -- Giles https://www.gilesorr.com/ gilesorr@gmail.com
