[Samba] Samba file server slowness

Below, you will find the pertinent information regarding my installation and
configuration regarding my samba install. I am currently trying to move my
companies file server off of windows and on to CentOS using Samba.
Everything works great, until I enable vfs_full_audit. Once I do that, the
server comes to a screaching halt due to the fact that when a user browses
to the mapped directory from their windows machine, it stats every single
directory. I need to be able to do logging due to industry compliance needs,
and it looks like the full_audit is what will get the job done best for me.
Any help would be greatly appreciated.

Also, I'm noticing a LOT of failures as it stats all the directories, it's
looking for desktop.ini. Again, any help would be appreciated. Thank you.
