[Samba] SMB data transfer performance on AD mode

Hi Everyone ! 

I note that all of samba AD server that i maintain are not so fast in terms of
data transfer, more specifically none of them go over 40 MB/s , one particularly
which i'm trying to find out why doesn't go over 20 MB/s , transfering
data using other protocols like FTP , rsync , rsync over ssh on any of these
machines i can easily achieve 80 MB/s ,i also can get the same on Samba if i run
it as a basic standalone file server or classic pdc nt4 mode, is this normal ? I
didn't try yet to deploy a basic file server and join a samba AD , is this
better than use AD server itself in terms of data transfer performance ?

Regards 
Dante F. B. Colò

ENODATA :-). We need much more information
on your setup in order to help.

Otherwise, this is equivalent to "my car won't
go faster than 40 mph, what's wrong ?"

There are a multitude of possible problems :-).

[Samba] SMB data transfer performance on AD mode

Hello Jeremy

Thanks for reply , i'm using samba 4.5.10 compiled from source on CentOS 6
and 7 running as AD mode on all servers, network infrastructure components are
all Gigabit ethernet 1000 BaseT, clients are all windows 7 and 10 machines,
i'll post below Samba build options and smb.conf of one of my servers. I use
full_audit module on many shares, but i don't see any difference in transfer
performance on shares that don't have this module enabled. I also used
Sernet binary packages before but after upgrade to newer versions compiled from
source i didn't see any performance loss or gain in terms of data transfer.
Any recomendations ?

ENODATA :-). We need much more information
on your setup in order to help.

Otherwise, this is equivalent to "my car won't

However, the first problem is that on the AD DC, smb signing is
required, which will make things slower than unprotected rsync.
