Bug Description
(I'm not sure where to file this so I've gone with boot)
I noticed with just feeling that Mandriva seemd to boot and finish bringing up the GNOME clock faster than Ubuntu Breezy. To this end I timed using a stopwatch the time it took both to boot.
Mandriva seemed to take 53 seconds and Ubuntu (after a fresh install with updates, near enough untouched profile) took 1:21 (so my gut feeling was right - Ubuntu finished almost 30 seconds later).
Figuring that it was due to Mandriva starting less initscripts I disabled the bits I did not need (bluez, evms, hplip, lvm, mdadm, mdadm-raid, pcmcia, powernowd, ppp). This saved a couple of seconds but nothing major.
Wondering whether it was because the Mandriva kernel was pentium optimised I switched to a k7 kernel in Ubuntu. This brought the stopwatch time down to 1:15 which is still 20 seconds slower than Mandriva.
I also used bootchart in an attempt to help better identify where the speed gains can be picked up. I shall attach the various boot charts that I have to this bug.
I hope that somehow Mandriva's speed ups can be cherry picked into Ubuntu because the difference is dramatic.
