Optimizing Boot Time: systemd-analyze blame Results

Hey Guys,

I am trying to improve / optimize my boot time and needed some help analyzing the systemd-analyze blame results. Just for some background, I have a 2019 X1 Cabon with i7 (Kaby Lake) and 16GB of ram.

The output is below:

Startup finished in 6.679s (firmware) + 2.789s (loader) + 1.228s (kernel) + 4.405s (userspace) = 15.103s 
graphical.target reached after 4.405s in userspace.

I’m not sure where to start, as I am a bit of a Linux newbie. Any help or assistance anyone could provide would be greatly appreciated.

Thank you!

apparmor is one of the services that is useful to optimize

Hi @A4orce84,

Here’s mine:

$ systemd-analyze
Startup finished in 21.995s (firmware) + 3.009s (loader) + 5.023s (kernel) + 7.347s (userspace) = 37.376s
graphical.target reached after 6.428s in userspace.

So I’m going to be honest with you when I say, ask _what so you want to “optimize”? Because it looks pretty optimized to me…

I just wasn’t sure if there are some services in my output that I can disable / kill?

systemd-analyze critical-chain is often what to look at to have tangible results in the optimizations.

how can we be able to answer this ? none of our crystal-glass-bowl does really work. for example, there is a “cups-service” for printers. do you use one ? if not you can disable and mask it. do we know if you’re using a printer ?

I think these kind of questions can help uncover those needs from how I understand it.

The answer: Yes, I use Cups and have a printer I connect to.

Well, I think you’ve got your answer, haven’t you?

the two links below are a good starting point but you need to get used to research a lot for yourself in linux-universe. that’s part of the game. nevertheless you can ask for specific questions but none of us can nor will predict your needs because this is impossible.
