FreeNAS server 3mb/s transfer to and from windows

[nfdevil]

Hey,

I've got a server running FreeNAS-9.2.1.5-RELEASE-x64 (80c1d35)
Specs:
CPU: AMD A4-5300 Trinity 3.4GHz (3.6GHz Turbo) Socket FM2 65W Dual-Core Desktop APU (CPU + GPU)
Mobo: ASRock FM2A88M Extreme4+ FM2+ / FM2 AMD A88X (Bolton D4) HDMI SATA 6Gb/s USB 3.0
RAM: GEiL Black Dragon 8192MB RAM DDR3-1066 CL7-7-7
Network Card: CSL - Gigabit LAN PCI Netzwerkkarte / Fast Ethernet Adapter 10/100/1000 DSL Realtek | 2000 Mbit (Full-Duplex) | 32 Bit | PCI Bus 2.2

Everything is going well, but the transfer speed to windows computers (thru CIFS) is really slow 3mb/s.
It was like that already before I bought this network card (was using a 100mbit before). Also updated my cables to gigabit.

The disks are fine too, I've tried them in a usb enclosure and they've reached around 40mb/s.
They're formatted as ZFS storage and I made a folder 'shared' on them.
Then trying to write on them thru my windows computer or reading from them, I get only 2.5-3mb/s.

I've drawn a plan of my network at home:

I guess it's just some tweaking that needs to be done to the FreeNAS, but I can't find what. I've googled for a week already.

I hope I can get some tips here or a solution.

If there are any questions or things I have to try out, feel free to tell me, if it can help, I'd love to try them

Thanks in advance,
Devil

BTW: I've also posted this on the FreeNAS forums, but maybe you guys have other idea's.

You absolutely positive you're only getting 3 millibits/sec? Capitalization counts here:
M=Mega
m=milli
B=Bytes
b=bits

Ow sorry, I meant 3MB/s

Thanks for noticing

I'm seeing that your NIC is a PCI card, is that correct? If so that's your bottleneck. PCI has only 133Mb/s bandwidth which is shared between all PCI devices on the bus. You'll never achieve full 1Gb/s speeds that way.

More confusion between "b" and "B". The slowest PCI bus is 133 MB/s. this is definitely not what is limiting the network transfer rate.

It is instructive to try an FTP transfer and see what rate you get. You should find it appreciably faster than SMB. NFS and AFP will also be faster, but your SMB transfer rate is abnormally slow; this does seem to be a common problem with FreeNAS and some chipsets.

I'm having the same problems as nfdevil. I first setup freenas on an old intel core2 duo machine with only 4gb of ram and I was getting 1-2.5 MB/s transfer speeds. I figured I would update to 8GB of memory, Intel Core i3-4130T, and an basic ASRock motherboard which has 10/100/1000 ethernet speeds. My problem still exists. Is it possible that when I installed freenas on the old box, certain settings were carried over to the new box as I did not do a fresh install of freenas, I just simply plugged in my old flash drive into my new box.

I've been searching forums for a long time, and I still don't know what to do since most posts about slow performance are in the 40-50 MB/s range...

Any help or ideas would be greatly appreciated.
