	There are quite a few messages on the archive about
different speed problems with regards to Samba serving files,
frankly speaking, I couldn't tell you one idea, I've been
fortunate enough to not have performance problems with my
Samba boxes, but all in all, it seems to be related with
several small good practices of oplocks, socket options and
other smb.conf parameters.

	Try to increase the debug level (log level) to 10, you
can also strace the process and/or capture the packages to try
to figure out something.

	What options did you tried? Can you post more details
about your smb.conf?

	First, maintainance, Samba2 is deprecated, no security
updates. It is better to "talk" with client machines in several
ways. It uses tdbs and/or LDAP, account policies, group mappings.

	I'm not sure if you are using LDAP, it is a powerful
resource, specially if you want to have PDC/BDC behaviour. The
Samba3 changes a few points in the course of his development, I
don't know what migration doc you read, but if it is not about
3.0.25, you need to check a few extra points from the release
notes that will solve a few problems.

	I hope this helps.
	Kind regards,
