Hi Jens, I have also had an issue with slowness in lots of small files. I'm using a 2.6.22 kernel with the most recent debian testing samba 3.0.26. I have been backing up a store of Maildir files that is around 120GB (approx 600,000+ files) and it takes around 24 hrs for this to complete. This is on cat5e cabling with Gigabit LAN such as yours. If I rsync this data it takes just under 2 hrs.
I posted to this list a while ago and had no response, and have not corrected the issue, so unfortunatly can not help. If you do get anywhere please let me know. Are there any senior samba guys or people that have fixed this issue that could comment?
