Ok, we are going to try this out and see if this makes a difference. The Windows server which is "faster" from Linux is running Server 2008R2, so I guess isn't doing encrypted SMB.<br>
<br>
Will report back next week once we've run some tests.<br>

<font size="3">i have seen reports from issues with RHEL 7 clients and SMB</font><br>

<font size="3">Hi,<br>
<br>
We've had some reports from some of our users that out CES SMB exports are slow to access.<br>
<br>
It appears that this is only when the client is a Linux system and using SMB to access the file-system. In fact if we dual boot the same box, we can get sensible speeds out of it (I.e. Not network problems to the client system).<br>
<br>
They also report that access to real Windows based file-servers works at sensible speeds. Maybe the Win file servers support SMB1, but has anyone else seen this, or have any suggestions?<br>
<br>
Thanks<br>

Simon<br>
