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.

    From cold shutdown, the server takes ~8 minutes by the time the IPMI has initialized, it’s probed all the RAM, initialized all the PCIe cards and run their boot ROMs, then actually booted Linux, brought all the RAID arrays online and done all the other stuff. It’s another 5-10 minutes until things are actually usable while the containers start. Only gets rebooted every month or so, and I’m usually doing something else while it’s happening so it’s not a big deal.

    Laptop is about a minute, but again, it’s in sleep mode most of the time so 95% of the time I’m not waiting for it to boot.
