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.
Will report back next week once we've run some tests.

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). 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?
