</div>I found performance increased slightly with jumbo frames turned on,<br>
between a Win 7 box and my main server running NetBSD/samba<br>
3.somethingorother.<br>
<br>
However.....<br>
<div class="im"><br>

><br>
</div>.....I did hit that problem.<br>
<br>
I have also had serious problems with realtek NICs in general though,<br>
replaced my home NICs with intel stuff (just the 1000/pro pci and<br>
pci-e cheap cards), everything is much more reliable now.<br>
<br>
I also needed a switch that supported it or things just stopped<br>
working (but reading your hardware specs it sounds like that's not a<br>
problem you'll have. ;) )<br>
<br>
Have you checked your SMB protocol level settings? The support for<br>
SMB2 is quite new in samba, and it certanly wasn't enabled as standard<br>
last time I checked. (This may have been a long time ago now.)<br>
<br>
In your smb.conf, in the [global] section, try 'max protocol = smb2'<br>
<br>
see if it helps.<br>
<br>
I get about 40MB/sec to/from my samba box to my win7 box, which I<br>
think is about the max my network supports (iftop watching a very<br>
simple client/server sending data across a socket seemed to indicate<br>
this speed too.)<br>

Ian<br><br></font></blockquote><div><br>Well I feel like the odd man out. My file server was recently reinstalled with ubuntu 11.10, I don't use jumbo frames as last time I tried to years ago it was a failure, and have not tweaked the smb.confg at all. Although I do see a comment in there suggesting the changes you guys have mentioned. I am able to write from win7 to a raid5 array of 4 2TB disks at 100MB/sec. Reads were at about 85MB/sec until I put in the sockets options above and that raised them to more like 90MB/s.<br>
