I’ve been working on my boot time lately, but I realize I really don’t have a good handle on what it should be. I am hoping some of you will share yours so we can all get a feel for it. I’m including some HW specs here also because I’ve heard it can be relevant:

64GB RAM, 2 x 2 TB NVME:

Startup finished in 9.922s (firmware) + 1.151s (loader) + 3.506s (kernel) + 4.006s (userspace) = 18.586s graphical.target reached after 4.003s in userspace.

Edited to add boot time detail

    # systemd-analyze time

Startup finished in 39.050s (firmware) + 6.680s (loader) + 993ms (kernel) + 3.519s (initrd) + 22.326s (userspace) = 1min 12.570s 
graphical.target reached after 21.680s in userspace.

    for me, most time is used until the bootloader shows up, because I had to disable “fast boot” in bios because it made some problems on rebooting. pressing enter in grub could speed up 5 seconds more ;-) gentoo, systemd, 2x2tb nvme, 32 gb ram, 4 hdds. could be faster, but it mostly doesn’t matter because I power on the system every morning but don’t use it right away

    edit: on my server, which is not UEFI, therefore has no “firmware” part:

    # systemd-analyze time
Startup finished in 1.814s (kernel) + 47.640s (initrd) + 36.602s (userspace) = 1min 26.057s 
graphical.target reached after 36.602s in userspace.

    and on my laptop, which boots fast AF

    # systemd-analyze time
Startup finished in 4.242s (firmware) + 14.631s (loader) + 1.737s (kernel) + 3.210s (initrd) + 5.136s (userspace) = 28.959s 
graphical.target reached after 4.936s in userspace.

      That seems like a lot of time in firmware! The laptop time is amazing though.
