[Samba] Aplication slow after migration

[Felipe Martinez Hermo]

    Hi, everybody!

I have been using samab on Debian for years and I have recently migrated 
my file server from version 3.0.14a-3sarge2 to 3.0.24-6etch4.
One or our applications stores its data in a shared folder. This data is 
distributed in over 29000 files of about 1k-40k and is so much slower 
when it runs on the new server.

I have thoroughly revised both smb.conf files, but can't see significant 
differences. I have read them so much that probably I'm already obfuscated.

I have tuned socket options, but can't see any improvement.
Any ideas?

Thanks in advance
