Now, from the same computer, Using JPEG insted PGF format to store
image in thumbs database. DB file have been remove before to rebuild
all thumbnails

rebuild time duration : 13mn 02s
database file size :

[gilles at pc-caulier photos]$ pwd
/mnt/data/photos
[gilles at pc-caulier photos]$ ls -al *.db
-rw-r--r-- 1 gilles gilles  1398784 2009-06-12 12:38 digikam4.db
-rw-r--r-- 1 gilles gilles 21109760 2009-06-12 12:51 thumbnails-digikam.db
[gilles at pc-caulier photos]$

Result are better than PGF, from speed and space consumption point...
