From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

What is a good boot time? (What's yours?) (lemmy.ml)

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

About twenty seconds from 'power button' to 'desktop' on my laptop, about two minutes on my desktop, mainly because it's got about 9 disks in it in various RAID patterns, and a discrete graphics card and fancy USB audio and all that shit needs initialised. Doesn't matter much, they both sleep / hibernate and rarely need restarted

Interesting - I also have a discrete GPU and a USB interface. Do these things add much time?

We're talking seconds, but on top of 'twenty seconds' then it's a large fraction of the total. The real problem is mounting disks in RAID for me, though - takes quite a while.
