: I'm not sure, but it might already add to the puzzle why ubuntu is faster for you. They don't have beagle and they use relatime by default.
I used relatime as is in the ubuntu's fstab and times are almost comparable. For Gimp it saved 5-6 seconds and also another apps start up faster ;-) Finally. It seems that relatime could fix it. So, what's next?
I did some highly unscientific measurements with default fstab options, then adding noatime and then realtime. Like this:
/dev/disk/by-id/ata-FUJITSU_MHV2080BH_NW78T652BFEN-part2 / ext3 acl,user_xattr 1 1
/dev/disk/by-id/ata-FUJITSU_MHV2080BH_NW78T652BFEN-part2 / ext3 noatime,acl,user_xattr 1 1
/dev/disk/by-id/ata-FUJITSU_MHV2080BH_NW78T652BFEN-part2 / ext3 realtime,acl,user_xattr 1 1
For me (fresh user on 11.1/kde4.3beta) there's no real difference with any of these fstab options.
Cold start FF (3.0.10): 8-9s Warm start FF: 1-2s
Cold start Gimp (2.6.2): 12s Warm start Gimp: 5-6s
On Mandriva 2009.0:
Fstab looks like this: UUID=7c2d957c-d69d-11dd-b9ef-c5218aa42eda / ext3 noatime 1 1
Cold start FF (3.0.5): 4s Warm start FF: 1s
Cold start Gimp (2.4.7): 9s Warm start Gimp: 3s
What is the full fstab entry that you use to achieve those results with realtime?
Watch out. No realtime, but relatime. But i'm talking about ext4. I don't know whether relatime has any influence on ext3. But try it. For ext3 try to add noatime and disable barriers. /dev/disk/by-id/ata-HTS424040M9AT00_MPA248Q2JL49AE-part1 / ext3 acl,user_xattr,noatime,barrier=0 1 1 have a look on this article http://vavai.net/2009/01/15/opensuse-tweak-increase-opensuse-speed-performan... and especially comment by Cristian Rodriguez Here you are my times.
