Hi,

 

I'm getting very slow transfer speeds (20mb/sec over SMB) and I'm wondering if I'm doing something wrong on the network side.

 

I have a TP-Link Deco XE75 system with three nodes. It is about a year old and supports Wifi 6E.

 

I have my Unraid connected to the base node using a new Cat-6 cable. From a laptop, I am getting about 20mb/sec. I've attached iperf3 results in both directions from a laptop on wifi to the server. The laptop is connected to the base node of the mesh network via Wifi 5.  Also, attached diagnostics are taken during a transfer of a ~2.5gb file from the same Windows laptop to the SMB share. The SMB is cache-first.

 

I routinely see people posting speeds of 100gb+ here, and even complaining that's too slow. I'm wondering if I am doing anything wrong.

 

Unraid running on an older Dell chassis, Intel Xeon CPU E5-2420 0 @ 1.90GHz, 20gb RAM, NIC capable of 1gb/sec.

 

Thanks in advance.

Wifi performance is lots of details - channel width, signal level, interference, plus meshing can halve speeds each hop. To be "wired" fast you need clear space, wide channels, and clear line of sight to the AP. Wifi7 brings some channel width magic to help, but you can get decent throughput on wifi 5 or 6. If you need to do lots of large file transfers, wired is the way.

Also I very much doubt lots of 100gb+ setups - 10gb is affordable if still not cheap and requires wired connections.

If you want to verify your server isn't the bottleneck you'll need a wired connection. I cap out at about 3.3gb/s to a raid10 SSD write cache on 10gbe (verified 9.8+gb/s via iperf3).

Thank you for the information.

 

I set up wired backhaul using MoCA and I'm getting much better transfer rates.
