Slow network on i4-Pro - vdg - 03-03-2016

I've tried almost everything I could think of but I cannot get more 277Mbits/sec with my box.

Here are my settings and my results:

I have all Cat5E cables in my network: both my NAS and my Cubox are plugged into a 1GB switch that supports flow control(unmanaged)

I am able to get from the same NAS around 800Mbits/sec from my Windows PC, so the NAS is not the problem...

I am running those tests because I am getting tons of errors playing Bluray content from my NAS. I have DTS-HD mkv files that require high bandwidth and it seem the Cubox is not able to get enough through the network..

There is a bus limitation of 470Mbps but I am not getting close to this number at all..any idea why??

UPDATE:
I have tried a Debian distro and guess what: I was able to get 470Mbps with no problem!
Now the Debian distro didn't have HW acceleration builtin..etc so I strongly prefer Openelec for my Kodi boxSmile

I wonder if some developer can look at the driver details from Debian 8 and see what is different and maybe update Openelec to fix this performance problem?
