The results were in contrast to mcatanzaro's from that blog post.
found no significant difference in boot times across F21-F25. With
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.
Thanks for investigating this. It's great that the results are mostly
favorable, except for this recent regression in F26.
Note that the reviewer who measured boot times across different Fedora
releases was HecticGeek, not me:
(He has newer measurements in newer articles.)
I wonder why his results differ from yours. I'm surprised that the
removal of the readahead daemon is not causing any problems in your
measurement, like it did for him. That's great, though.
So I'm *still* not sure what's behind the very slow F23 boot
reported, but my test couldn't reproduce that slowness or show any
significant difference between any of the releases from F21 to F25.
difference between F25 and F26 might be worth some independent re-
testing and deeper analysis.
I've since switched to using an SSD and it boots to GDM in 15 seconds,
so it's not bothering me anymore anyway. I was worried about boot time
without readahead for spinning disk users, but since your results show
no difference, perhaps we should not bother.
