Slow system boot time

[kian]

Hi, unfortunately my English is poor
I have a problem, thank you for your help
The system manjaro takes 5:38 seconds. It goes up very slowly. What can I do?

Try installing haveged and see whether it makes a difference.

sudo pacman-mirrors -f 5 && sudo pacman -Syyu haveged
sudo systemctl enable --now haveged

See it if speeds up the boot process.

With thanks for your attention
The speed increased
1:38
But considering the hardware, I expect more
Come up sooner
I used to use Windows 10, it takes less than 30 seconds, but now it works very slowly inside Linux

System takes a long time to boot

If you’ve got errors like Failed to start Network Manager Wait Online. you can try removing systemd from passwd and group in /etc/nsswitch.conf as described here
Update: If you can see the line
dbus-daemon[1453]: [system] Connection has not authenticated soon enough, closing it (auth_timeout=30000ms, elapsed: 45146ms)
in in your dbus log ( journalctl -b -u dbus ), the new/better workaround is to switch cups from service to socket as described here:
systemctl disable org.cups.cupsd.service
systemctl enable org.cups.cupsd.socket

How can I disable additional services that are not required?

That’s not bad. My system boots up from the GRUB menu to the SDDM login screen in about 10 seconds.

[Alfy]

i prefer

systemd-analyze plot > plot.svg

and then open in a browser.

[joeboris]

Can I mask the systemd-journal-flush service and run journalctl --flush later manually?

Following are the steps to solve this:

1. Do a flush journalctl --flush
2. Remove/Move the directory /var/log/journal
3. Set Storage=auto in /etc/systemd/journald.conf
4. Reboot the machine

You should see an improvement in the boot time.

[kian]

The speed of the system changed a lot, the speed improved. Thank you

Permission denied

You need root privileges to execute that command. Open up a terminal and type…

sudo journalctl --flush

Thanks, I just realized

I’ve used haveged for a ton of stuff but why would it diminish boot times?
Is that because:
1.244s systemd-random-seed.service

[Aragorn]

Yes. haveged is a random number generator, and some processors are not capable of generating enough entropy at boot time. This entropy is needed for cryptographic purposes, such as the login procedure and the mounting of encrypted volumes.
