My machine is running samba 4.0.3 inside a DomU of Debian Wheezy.

Following the Samba AD Howto and running Samba 4.0.3 successfully but with one pretty serious problem.  When I try access the folder with 1000 files, the speed is *VERY* slow.

After employ log level to 3, log.smbd is flooded with:
=============================================

==================================================================

I have googled the mailing list and I am sure that the iconv library is installed correctly and also pass the test for ACL in filesystem in linux listed here (https://wiki.samba.org/index.php/Samba_4/OS_Requirements#Testing_your_filesystem).  Also, the folder permission is 770 and owned by root:root.

Can anyone help?
