Terrible Speeds for NAS

[boatlesshoes]

Hi, I have been trying to set up a NAS using nas4free and I've been getting about 5-7MB/s transfer speeds which seems incredibly low from what I've seen. I have done some troubleshooting and have run iperf and dd. I have two 2TB drives in ZFS stripe with dd reporting ~200MB/s for both read and write. I have tried a different 2TB drive in UFS and I still get the same speeds.

For iperf, I have machines A (wired), B (wireless), and NAS.

With iperf from A to NAS I get 5-7MB/s.
With iperf from B to NAS I get 3-4MB/s.
With iperf from A to B I get 6-7MB/s.

Is the issue something with my router or some of its settings? I have an ASUS RT-AC66U router.

what hardware are you using?

forget about good wireless performance.

The test for wireless was just that the laptop was the only other machine I have to test the local connection. The NAS is for my desktop only.

I tried setting up a server on two separate machines actually. The first was an AMD E350 1.6GHz dual core (GA-E350N-USB3) with 8GB of RAM. The other machine I tested was an Intel i5 750 (GA-P55A-UD3P) with 8GB of RAM.

I also have an Intel EXPI9301CT but speeds are no different with or without that card in.

The problem could be anywhere so I guess the first thing is to simplify the setup.
Set up a static ip address on your NAS, and a static ip on your test PC both in the same subnet. Plug them together directly.

Now run the iperf test - if the performance is good the problem is elsewhere.

btw - is anything in your setup old technology? - 7MB/s sounds would be a reasonable performance on a 100baseT network

Static IPs set and connected to each other I get 11.3 MB/s (95 Mb/s). All the ports are gigabit capable, is there a setting I need to adjust?

Could you define old technology? None of the machines are more than a few years old. Desktop has a 3770K.

Really I was just asking if there might be something in mix that was not GigE capable. So test machine directly connected gets almost spot ton 100Mbit/s?

Mist likely problems:

• replace the cable - 100baseT can work with a damaged cable, GigE need all four paris working
• Test machine NIC- I assume its windows, in control panel / network / property list / set to duplex and auto detect (location varies by version)
• Nas4free nic - Network|LAN Management media - set to 1000baseTX, Duplex - set to full duplex, set MTU to 9000 if you your other devices support it

routers can go bad.
my son's GB Cisco "small business router" [like a rvs4000 but with WiFi ]
permanently defaulted to 100-T after too much age or near by lightning.

do not rely on WiFi for any test, plug the laptop in to the LAN
speeds below are with wired 64 bit hardware Gb LAN with out any tuning
once with a bad cable my router defaulted to 10-T; that was way slow.
