[Samba] XP Slow Downloading files

I have added a Samba 3 machine as a BDC and used the net rpc vampire command
to copy all of the users and machines.

For some reason, only Windows XP clients are slow when downloading files
from the Samba BDC.  NT and 2000 clients are fine.  When an XP client
uploads a file, it takes almost no time at all.

I've been searching but haven't found any answers.

Here is my smb.conf
