My iperf speeds between my test laptop and my FreeNAS server are very slow, around 170-180Mbits/second
I'm not sure where to go from here, any help would be appreciated.
System:
Build FreeNAS-9.3-STABLE-201602031011
Platform AMD Opteron(tm) Processor 6128
Memory 32740MB
System NIC setup:
My motherboard has 4 Gigabit ports:
The Intel 82576EB is a dual port NIC wired up on a x4 PCIe port.
The other two ports are each a Intel 82574L connected to a x1 PCIe lane.
The system block diagram is Figure 2.2 from this document: http://www.tyan.com/manuals/S8230_UG_v1.0_06212012.pdf
Client/Server setup:
My FreeNAS box has a 6 foot Cat 6 network cable (new from package) running directly connected from em0 to my laptop Gigabit port.
I manually set a static IP on the FreeNAS box as well as the windows box.
FreeNAS config data:
dmesg output:
Note, I assume that the igb0 & igb1 NIC is the 82576EB since both of the ports are on the same pci bus.
Things I have changed:
Things I need to do for troubleshooting:
Do any of the settings above look off? Any settings I can try with my FreeNAS install?
Code:
[root@freenas] ~# iperf -s ------------------------------------------------------------ Server listening on TCP port 5001 TCP window size: 64.0 KByte (default) ------------------------------------------------------------ [ 4] local 192.168.1.12 port 5001 connected with 192.168.1.3 port 53569 [ ID] Interval Transfer Bandwidth [ 4] 0.0-60.0 sec 1.27 GBytes 181 Mbits/sec

Note, I assume that the igb0 & igb1 NIC is the 82576EB since both of the ports are on the same pci bus.
Things I have changed:
- I tried 3 different network cables per the suggestions in other threads in the FreeNAS forum.
- I have tried all 4 network ports, none show a increase in speed.
Things I need to do for troubleshooting:
- Try another client laptop/desktop machine.
- Take this client laptop and see its iperf performance with other machines.
- Get a Intel PCIe network card and try
Do any of the settings above look off? Any settings I can try with my FreeNAS install?
