    systemd-analyze

    Hi everybody, hi Michael.

    I just wanted to let you know that systemd has a really easy and nice tool to analyze what is slow. Sometimes the slow task might even be non-blocking, so that user perceived boot time is not as slow as stats declare.

    To have a better detail of boot times and slow services you can use:
    Code:
    systemd-analyze time
    and:
    Code:
    systemd-analyze blame
    You can even get a plot of boot with:
    Code:
    systemd-analyze plot

      BTW, a good guide to using the tool can be found here:
      When I’m checking the performance of my fedora, I found that my fedora takes 36 seconds to boot completely which is double the value of expected (15s) boot-up time. I decided to optimize my f…

        for me fedora 18 boots quickly but the GDM loads in about 30 seconds and once i log in the desktop takes another 30 seconds to load...its hardly usable this way, especially cause i installed it on an ssd

          I've seen several people report this and my laptop seems to be hitting it: I believe it's actually gnome-shell hitting some kind of timeout during startup. If you just restart gnome-shell with alt-f2 'r', does it also take a long time? I'm planning to work on debugging this with the desktop devs soon. This could well be the bug that hit some of the systems in this benchmark.

            unfortunately i cant test right now, my hd6870 broke and im lazy to install legacy drivers for my current hd4670, i will receive my hd7870 in a week then i can report back with more info, altho i doubt its gnome-shell, ive installed lightdm and mate-desktop because i hate gnome3, and completely removed every gnome3 related package and altho my dm delay is somewhat solved, mate-desktop still takes ages to load

              So I found time to look at this again yesterday, and found that for me, the problem seems to be in nautilus, and appears to happen only when the network is down:



              Is your network down when booting the system? If so it could be the same thing; nautilus may be coming up in MATE.
