This is my first post to these forums. I've been playing with Ubuntu for a while now and have used these forums to help me out with many problems, unfortunately I cant seem to fix my current problem.
I've setup a box (HP Proliant Microserver N36L) running Ubuntu Server 64bit 12.04.1 LTS to act mainly as NAS and I'm experiencing extremely slow network speeds.
I know the various file sharing protocols will be slower than raw speed but my problem seems to stem from the raw speed.
Firstly my hardware: HP N36L has onboard gigabit lan. Using cat 6 cable connected to 10/100Mb capable router, then wireless to Apple Macbook.
Right so my network interface is reduced to 100Mb(router) but surely I should still be getting better results with iperf than this:
In fairness this result is pretty good I'm usually hitting around 5Mbits/sec
Server listening on TCP port 5001
TCP window size: 85.3 KByte (default)
[ 4] local 192.168.1.69 port 5001 connected with 192.168.1.64 port 56451
[ ID] Interval Transfer Bandwidth
[ 4] 0.0-10.0 sec 13.6 MBytes 11.4 Mbits/sec
Here is some more information I think is relevant (cant find any problems in any of it):
dmesg | grep eth0:

UPDATED - this might help aswel!

I'm sure there's something I've missed. At the moment I'm using netatalk to share with my macbook as I understand it's faster than samba but it's pretty much useless to stream videos from at these speeds.

I very much hope someone out there can help. Every other post out there seems to be someone with good iperf results and poor smb speeds. I've just got terrible iperf results!!!
