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?
