So, funny story: my todo list has this item, which I'm crossing off with this mail: compare f21 / f22 / f23 boot on rust: https://blogs.gnome.org/mcatanzaro/2016/01/31/on-boot-times/#comment-120 It's only been on my list since 2016-02-06, no big deal, right? However, never let it be said that I'm a liar! I *did* finally get around to doing it, plus I included F24, F25 and the current F26 nightly compose as well. I tested each by installing from the x86_64 Workstation live image to my test box, which has a low-end AMD CPU (A4-7300), 8GB of RAM, and a Seagate 500GB SATA hard disk (not an SSD). I created a user during the install (so first boot wouldn't hit gnome-initial-setup before gdm), then measured the boot time from hitting 'enter' on the bootloader screen to GDM appearing fully loaded. I then measured the time it took from hitting 'enter' on the password prompt to GNOME appearing fully loaded. Then I rebooted and did the same measurements again (to see if second boot differed significantly from first boot). I did not use encryption. The results were in contrast to mcatanzaro's from that blog post. I found no significant difference in boot times across F21-F25. With only one exception, pretty much every 'boot to GDM' measurement came out at 30 seconds, give or take a second or two, and every 'GDM to GNOME' measurement came out in the range of 6 to 8 seconds. The exception was the first boot of Fedora 21, which took a little over a minute. The second boot took 29 seconds, though, in line with all other tests. However, F26 does seem slightly slower than F21-F25. First boot to GDM for today's F26 nightly measured at 42 seconds. Second and third boot measured 39 seconds. GNOME load time was 8-9 seconds. Looking at the systemd-analyze info, I don't see any obvious single 'culprit', it seems more like approximately the same stuff is happening during boot, it's just all taking a bit longer. So I'm *still* not sure what's behind the very slow F23 boot Michael reported, but my test couldn't reproduce that slowness or show any significant difference between any of the releases from F21 to F25. The difference between F25 and F26 might be worth some independent re- testing and deeper analysis. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Twitter: AdamW_Fedora | XMPP: adamw AT happyassassin . net http://www.happyassassin.net _______________________________________________ desktop mailing list -- desktop@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to desktop-leave@xxxxxxxxxxxxxxxxxxxxxxx
