Manjaro boots really slow

Support
1

Manjaro boots really slow on my system (takes around 30-40 seconds) , which other distros like Ubuntu(8-12 secs) and Windows(7-11 secs) don’t. I tried multiple different install configurations, but none did really help:

  • Legacy Boot with and without a LUKS partition on a NVME and normal SSD.
  • UEFI Boot with and without LUKS partition on a NVME and normal SSD.

The output of systemd-analyze blame is basically always the same: The system takes a lot of time to do something with the boot drive:

So, how can I speed this up?
Thanks in advance.

Isn’t that more than obvious ?

Don’t use encryption…

Uh, I said in my original post that the same issue happens even without encryption…

However… you could check the scheduler:

grep "nvme" /sys/block/*/queue/scheduler

For better performence, you could switch it to none on a nvme : Improving performance - ArchWiki

see this

  • are you using a pci -Nvme card ?

I have the issue on both the NVMe drive and normal SATA SSD.
Also, what logs do you want?
Changing the scheduler only worsens the situation.

The way I interpret the output:

is that systemd-random-seed.service is slowing you down by forcing dev-mapper to wait (by 15.433s). Am I correct?

I actually read it more as: Dev mapper takes 16 seconds and then random seed service 1.2 seconds. You can also see this on the graph in my last post.

I also have an update to report: Endeavour OS has te exact same issue for me. The boot device also takes up about 16-17 seconds of the boot time.

After changing a lot of things like removing the fsck hook, trying different kernel parameters and disk schedulers , which all didn’t help, my conclusion is that is must be caused by the kernel. (Garuda uses Zen kernel)

  • What is the output of grep COMPRESSION /etc/mkinitcpio.conf ?

  • Did you compare other Linux Kernel 5.10 or 5.4?
