Tweaking startup times

Support & Help Requests
1

I’ve been tweaking my system in order to speed up start up time. The best I’ve achieved is:
Startup finished in 6.977s (kernel) + 20.852s (userspace) = 27.830s

Possibly I’m at the limit of my system - core i7 960 @ 3.2 Ghz; 12 GB memory; ATA ST31000528AS
it seems to me that 20 seconds to reach user space is a bit long.

Thoughts / ideas?

Hi Peter,

I don’t worry about such things to be honest and I have never really timed my PC’s boot times, I have noticed that shutting down can take some time but who cares!. :smiley:

I’m not overly concerned … I’m using this as a learning experience for systemd

My brain is far too small for such matters!. :smiley:

Or just quite possibly more discerning :wink:

I don't know whether or not it is discerning but it just doesn't bother me at all to be honest!. :smiley:

Use an SSD as your system drive I have a Clarkdale i3 with only 8GB and my system is reporting Startup finished in 2.541s (kernel) + 9.836s (userspace) = 12.378s Interestingly enough it takes noticeably longer to boot from hibernate because I put the swap space on a spinning drive.
