Don't miss understand what I trying to say. What the samba team has done 
with 4.x has been great.

In the testing that I have done on our production file server cluster if 
I run transfer tests with 3.6 vs 4.1. The 4.1 is 50% slower than 3.6!!! 
I am not the only one seeing this. We just built 2 new file servers 
running CentOS 6.5 running pacemaker, drbd, samba and ctdb to provide 
all file and profile sharing. This was built with 4.1.7. We finally had 
to go back to 3.6 because of the performance problems. We also had 
problems with winbind and I know that is being worked on.
