It seems people are noticing how much faster 9.04 is at booting.
I happen to have 2 SSD disks, one in my desktop and one in the laptop. I measured both my machines with bootchart, the laptop is set to autologin (I am unsure when bootchart stops measuring or if that matters).
The desktop is a 32gb Samsung SLC drive: 12.54 seconds. Not so bad. This is kind of a mongrel system though, I am always installing and removing things, which is why you see leftover exim stuff. I also use a spinning disk as my /home, but I do symlink things like .gconf and .config that get read on boot to make that fast. (And yes, moving .gconf from the spinning disk to the SSD made a huge difference “feel” wise, I should have measured that.) Either way, it’s not a good candidate for measuring stuff, so take that with a grain of salt.
My Lenovo X200 has an X25-M (Not the faster E mind you) – 7.61 seconds. This is basically stock Ubuntu 9.04 as of this morning. Quite acceptable.
For those of you in the back going “Come on now, you have SSDs, I am just a normal person with normal disks, no fair!” I have an old athlon system in the other room and a hp 2510p laptop with a notoriously slow 4200rpm drive and I notice the difference on both of them. Unfortunately you’re going to have to take my word for it since I never had bootchart installed on them until just now. Even in Jaunty the boot time of the 2510p is 27.98 seconds, just to give you an idea …
I, too, have noticed a significant speed jump.
It used to take 1:45 seconds from a cold boot to usable desktop on my Eee PC.
With Jaunty, it’s not 1:00 exactly.
And when I say 1:45 or 1:00, I mean from the moment I press the power button to the moment my Firefox has autostarted and is usable. I don’t mean when the Gnome panel appears.
Oddly enough, once booted my laptop takes donkeys’ ages to get to a desktop. I don’t know why, though (my desktop doesn’t have the same problem and I’m wondering if CPU scaling is the problem).
I find (especially on older installs) that blowing away .gconf after an upgrade fixes login time. You’ll have to redo your app settings, but you won’t lose data.
Is this something that that new Computer Janitor program does automatically?
Jaunty really boots faster than Intrepid, I definitely noticed that.
Unfortunately the login became way slower at the same time so the situation didn’t really improve for me.
This is he time my laptop (5400 rpm HDD, 3GB ram, 2,2 core 2 duo) needs until I can work with it (i.e. open a program):
Pressing power to GRUB: 8s
Starting and loading GDM: 44s
Loading Gnome and panel: 50s
I have no idea how ubuntucat manages to get a working firefox on his eee pc in half the time it takes for me, but I am really envious.
Ouch, that looks bad. Like I told graham, blowing away .gconf always does the trick for me. Actually, move it out of the way and see if that helps.
IIRC bootchart stops logging the moment GDM finished loading. I too am booting really fast in Jaunty, but I think that some attention needs to be put into how long it takes to have a functional desktop once the login begins. With boot speeds of 20 seconds and lower, login is now a significant chunk of the starting up process.
What’s maco doing wrong then? http://identi.ca/notice/3312833
No idea, I suspect a bootchart would explain what’s going on there.

I don’t have any left from Hardy though.
Yes, I had KDE4 installed on Hardy and the entire time I had Jaunty. Yes, I had all that MySQL stuff installed for KDE4.
For some reason, Bootchart is no longer generating charts (just tarballs of logs) when it boots (last chart was March 10). I have no idea why. But it means I can’t get anything more recent.
Oh, and I know the hostnames don’t match. I swapped the hard drive from ada to betty and forgot to reset the hostname until sometime in February.
[...] the meantime, give Jorge Castro’s post about Jaunty’s quick boot times a read. Almost makes me want to empty the checking account for a new SSD drive for my Thinkpad T61p. [...]
Bootchart tells me my Jaunty boot time is 1:72, which leaves be a bit confused.

I am pretty sure it doesn’t. Still, it’s not a fix, I’m just working around the issue of crap building up over time. Hopefully dconf (see gnome desktop devel list) will be more robust.
