long systemd firmware boot time

PhilSmith · 2021-01-13 11:26:35

Hello everybody,

any thoughts on this output of systemd-analyze?

Startup finished in 15.384s (firmware) + 1.237s (loader) + 1.198s (kernel) + 630ms (userspace) = 18.450s 
graphical.target reached after 552ms in userspace

systemd-anaylze blame showing the following (< 10 ms cut off):

                                            `--.slice @142ms

15 seconds for firmware bootup seems a lot to me.
Anything I can do to improve that?

What I have already tried:
turning on fast boot, disabling legacy usb support, disabling iommu

My specs are in my signature, bios is latest (beta) version and ram is overclocked with the standard profile to run at 3600 MHz.

Thank you all!

This "firmware" number is happening outside of Linux and initrd and bootloader. There's just the UEFI/BIOS menu settings that can do something. On my board here, I can do nothing. It was the same on my previous boards. Maybe changing the RAM to a crappy 2400MHz speed with default JEDEC timings might get you two seconds?

Thanks for clarifying that this has nothing to do with my arch setup.

Well, when I disable d.o.c.p. I get this:

Startup finished in 11.157s (firmware) + 1.222s (loader) + 1.193s (kernel) + 723ms (userspace) = 14.296s

Definitely better, but I don't know what this tells me.
Some guys recommend to manually edit the ram timings and so forth to the exact values of d.o.c.p.
The fact that this is done manually is supposed to solve these issues apparently.
Well, I'm gonna try if I have the time.

Still, 11 seconds seem like a whole lot to me.
If someone has other ideas, please let me know.

On a Prime X470 Pro with Bios 5809:

Startup finished in 13.337s (firmware) + 1.479s (loader) + 2.243s (kernel) + 5.177s (initrd) + 11.425s (userspace) = 33.663s

With previous UEFI versions, this took much longer. Up to 30s from power on to beep.

10 year old sandybridge boards needed 10s from power on to auto-login, sad but true.

It tells you that, as hinted in an earlier reply, slowing down your RAM has helped this particular issue.

PhilSmith · 2021-01-14 13:29:07

Well this feels to become more like a "can't do much about this anyway" issue.
I will hope for some improvement due to future bios releases by asus.

Well, slowing down RAM speed surely helped a bit, but I think there is more lost than gained for a few seconds here.

On a B550M Gigabyte board I just bought for my mother, I get 6 seconds bios time, but well ...
It seems to be what it is.
Thank you for your thoughts!

Realistically that's all you can hope for. Unfortunately it has very little chance of actually happening....
