[Samba] Slow Directory listing for large number of files

[Matthew Enger]

Hello,

I have a samba server which has a directory with 11764 files. (The
program stores information about jobs and each job has 3 files, nothing
I can do about it).

When I do a listing of that directory using smbclient, it takes 15+
seconds to complete, same thing on Windows XP.

Does anyone have any ideas on how I can speed this up?

I did a log on log level 10, it is accessible at
http://www.enger.org/backup.log (10761841 bytes).

Timeline I have noticed:

If anyone has any ideas that would be great.

I have tried Samba 2.2.7a and 3.0.2 which both have the same issue. Log
is from 3.0.2. Running Fedora Core 1 and ext3 file system.

Thanks,
