Cifs vs Nfs speed

[#1]

So with my new graphics card disliking Linux, I am dual booting w7 & Mint.
My "Server" has onboard gib nic. Connected to the same pc using Mint, I get ~90Mb/s across the wire. rebooting into M$ and from a Cifs share it was 20-30Mb/s. (same shares via nfs & cifs)
Any ideas on why or is Cifs just SLOW.

[#2]

Mint is Linux.
Why not try CIFS on Linux it may be OS related.

[#3]

I know absolutely nothing about CIFS but a quick Google search threw this my way.

Well I have called it CIFS since I was a M$ specialist, hard to stop doing so. '-)
Just tried and YEP it is CIFS (or SMB) that is SLOW, to this PC running Mint <40Mb/s, copying using NFS 95Mb/s.
Getting a FREE NFS client on M$ is as bad. I have enabled client for Unix, but you need to run a cmd prompt as Admin to map a drive, and it stays mapped even though it is not accessible after a reboot.
Ahh well will just have to suck it and see how I get on.

The package description for nfs-kernel-server says:-

Quote

The NFS kernel server is currently the recommended NFS server for use with Linux, featuring features such as NFSv3 and NFSv4, Kerberos support via GSS, and much more. It is also significantly faster and usually more reliable than the user-space NFS servers (from the unfs3 and nfs-user-server packages). However, it is more difficult to debug than the user-space servers, and has a slightly different feature set. This package contains the user-space support needed to use the NFS kernel server. Most administrators wishing to set up an NFS server would want to install this package.

What version of Samba is on the server? Can you post your smb.conf file?
What performance do you get from the CIFS/SMB share on a Linux client? (i.e. is this a Linux vs Windows performance issue, such as antivirus scanning files, or really an NFS vs SMB issue)

The SMB version is the lastest from the Mint repo's. The speed is the same, see above, I re-did the test under Mint. 40 vs 95Mb/s.
Version: 2:4.1.6+dfsg-1ubuntu2.14.04.7

I'm currently transferring 250GB over a CIFS share via a particularly slow wireless connection to a Windows 8.1 PC.
It manages around 1MB/sec, so I may be some time...
It seems particularly slow on bunches of small files - I suspect its asking Linux if it has read authority on each file & it performs especially badly at this.
I can't just do a restore, since the files are held on a external disk formatted to use LVM.
Windows can't handle LVM disk.
