It'd make interesting reading to see what different people are getting in terms of boot time, as it relates to system specs, optimisations etc.
For me it takes 65 sec from turning the computer on, to seeing the gdm login. This is with a 10 sec delay in grub, so it can be 55sec. My gnome desktop loads in about 3 sec after that.
I'm running Hoary on a P4 2.6GHz box with 1Gb RAM and a Western Digital 160Gb drive 7200 rpm.
I've stripped out all sorts of unwanted services (especially checkfs.sh which took 30+ sec to check my disks every boot) and enabled prelinking. I also edited /etc/init.d/rc to include an & after $i start , so as to start later services in parallel.
The last few lines...
I'm running splashy, which might add a couple of seconds to boot time but is worth it for looks!.Code:startup $i start & ;; esac done fi # eof /etc/init.d/rc
Ubuntu certainly doesn't have the fastest boot time of any linux I've used, but I've also seen a lot slower. On the flip side, once it's up and running it seems pretty snappy to me!
