Like many I ran into the slow winXP client when attached to a samba server. Access times were extremely slow and windows explorer was almost unusable (especially if there were a large number of files in the directory).
The XP users authenticated properly and rights were applied as expected via the samba configuration. Every thing worked properly... except really slow.
I went through all the usual suggestions found on various lists (changes to the registry, shutting things off, reducing the view in explorer) as well as doing some serious linux and server tuning. All provided minor improvements but nothing significant until.......
I noticed that I (as an admin) was not having the problem (even when I was on an XP box). So I added the group in question (engineering) to the "admin users" and presto... all latency is gone!
This works in this particular case as the engineering group has all rights to this share, but if they didn't I'd still have the problem.
How can this be fixed properly....
I'm guessing that unless a user is admin the access rights are checked against everything in the directory (which can take a bit of time). If they are an admin (to the share) samba blindly gives them access, thus avoiding the long access lookups.
I would think that there would only be the need to check access on two things.
1. the directory in question and
2. the file being accessed.Below are the changes and share setup...
changed: admin users = @admins to: admin users = @admins,@engineering,@fixedprod
[eng_shared] comment = engineering shared files path = /export3/eng_shared valid users = @users write list = @engineering,@fixedprod,@admins # general settings -- all shares should use these force user = %U admin users = @admins,@engineering,@fixedprod hide unreadable = yes browsable = no public = no writable = yes printable = no create mask = 0770 directory mask = 0770
