I've read up on all the threads regarding slow transfer speeds, but I can't seem to improve it.

 

• SMB transfers hover around 10-20mb/s, occasionally spike to 100mb/s and occasionally crater to 3-4mb/s. For the most part 20gb will take about 20-30 minutes.
• I've observed this from both a new M3 MacBook Pro and and older Dell XPS. Both have SSDs as source drives.
• My hardware is old, Intel Xeon CPU E5-2420 0 @ 1.90GHz, 20gb RAM.
• I have an Ubuntu VM running at the moment.
• Windows reports local network operating in the 800mb/sec range.
• Parity is paused.
• Turbo Mode enabled.
• Transferring to cache-first share.
• iperf results are slow (see screenshot)

 

Since I'm observing this from 2 computers, and iPerf is not awesome, I'm assuming this has to do with Unraid or the hardware. Could this be a result of old hardware?

 

Attached diagnostics taken during a 20gb transfer of images.

 

Thank you!

Iperf results confirm there's a network issue, is this cabled gigabit, 100Mbit or WiFI?

Looks like you are only connecting at 100 Mbps.

 

note that gigabit LAN can silently degrade to 100 Mbps if any of the twisted pairs between client and host are not making contact.   Can be due to bad cable or a port being faulty.

This is over a home wifi mesh network, a relatively new Deco system.  Laptops are on wifi (one on wifi 6). Unraid is Cat6 cabled to the base station.

 

I can confirm it is a network issue. I set my Windows laptop as an iperf3 server, and pinged it from my other laptop. Speeds were comparable to speeds between the computers and Unraid.

 

Thank you - I'll take this up with TP-Link management, as they say.
