[Samba] Question about performance difference between samba4 versions

[Dennis Kramer (DT)]

Hi,

Can somebody maybe explain to me why there is a (huge) difference between 
the default samba package in ubuntu trusty (4.1.6) and the from source 
compiled stable version.

I cannot find the reason why the ubuntu version is so much faster when 
doing a move (50 items p/sec) of a bunch of files and doing the same move 
on the compiled version of samba (2 items p/sec).

Generic transfer rates (normal read/write operations) are no problem, I 
only notice the drop in performance rate while doing an explicit move of 
(50+) files from one subdirectory to another. Source and target share is 
the same. Such a move operation should be close to instant.
Did I miss something?

Grt,
