Hello everyone!
I'm currently having a network speed problem on my OMV NAS and it's driving me crazy..
I've managed to setup the basics of my OMV server, with working SMB sharing between the server and my Windows laptop, but when I try to transfer some files to and from the NAS the speed is limited to 10-40 MB/s. I know I should have Gigabit speeds (ideally), since every component of my network is Gigabit capable, but no matter what I do or try, the transfer speed is always the same. I tried a thousand guides but none has solved the problem.
Here is what I manage to find out:
1) Ethernet connection of my laptop is rated up to 1 Gbit/s
2) The cables I'm using are all cat 5e
3) The router is also rated up to 1 Gbit/s
4) The network card on my OMV computer is also rated up to 1Gbit/s speeds

I've tried iperf tool between the machines in my LAN network and this is the result:
root@thevault:~# iperf -c 192.168.1.22
------------------------------------------------------------
Client connecting to 192.168.1.22, TCP port 5001
TCP window size: 85.0 KByte (default)
------------------------------------------------------------
[ 3] local 192.168.1.200 port 41376 connected with 192.168.1.22 port 5001
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 1.10 GBytes 947 Mbits/sec
So, everything seems to indicate that I should have Gigabit transfers between my laptop and the OMV server, but every time I try to copy some files (no matter how many or how big) the speed is limited to 10-45 MB/s.
At this point I have no idea what could be the problem..
Thank you for any help!
