    Phoronix: Fedora 18 Systemd Boot Performance Is Mixed

    In addition to open-source graphics driver benchmarking, another area being explored with the recent release of Fedora 18 is the boot performance. Here's some initial results from three systems compared to the Spherical Cow's predecessor.

    So boot perfomance depends on hardware config. The regressions can be found by using systemds blame/analyze tools.

      I don't think there was a regression in the user space. I think the way systemd measures load times for the components changed from F17 to F18. There's no way a default Fedora userspace is loading in 4s with a rotational disk.

        On my hardware, the total boot time is noticibly faster in 64-bit Fedora 18 KDE.

          Cannot confirm

          On my X220 with SandyBridge Hardware and an SSD, Fedora 18 is booting faster in my opinion.

          I have five systems with Fedora 18 running upgraded from Fedora 17. On none of them the boot time regressed in any noticeable manner. I rather think it got farther, altough I did not measure it.

            Suspend to disk?

            Just use that and have your system up in less than 10 seconds...

              Fixed that for you (when using the NVIDIA driver at least)... this is why I never suspend or hibernate.

                So... man power should think to solve hibernation problems rather than boot speed.

                Anyway that's strange, i always used hibernation (first tuxonice, then vanilla) with:
                7900gt,9600gt,9800gt and ion first gen without problems across kernel releases for years.

                  This is not a good article! It would be interesting where the problem exactly is! As "funkSTAR" said, you can analyze this with systemd's blame!

                    This realy sucks, if it is practicaly slower in Fedora 18 as well.

                    I have not realy felt the need for a SSD, because Fedora 17 boots realy fast en feels realy responsive for file lookup. For example when I mount a Windows partition, Rhythmbox instantly displays all music that's on that drive, and scrolling and previewing a map full of pictures is so fast that I can't notice any slowdowns using a HDD.

                    I hope that once I install Fedora 18 on my new (refurbished) desktop with a standard Seagate Baracuda 500GB, this isn't making me downgrade to Fedora 17

                      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

                          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
