Terrible speeds when copying from the array

[madmanx]

I am totally stumped as to the cause of the speed issues when I copy files or move files from the array to my PC, I have done some trouble shooting, using Iperf3 and when I set the server as the client the speed is attrocious see attached. I have tried this from my Pfsense box, android phones, windows 10 pc multiple places and all the same issue. What could be the cause I have tried changing the MTU, changing the NIC using an Intel NIC, turning off bonding. I am honestly stumped. If I change the unraid server to the server then the speed is totally fine.

You should post your diagnostics

[Tom3]

The retr column shows the number of retransmitted TCP packets. The first row

in your transfer shows 56 retries, which is so high as to appear essentially non-functional.

So the question: what is the cause ?

 

Some things to check:

1. Ethernet cables.

2. Any intervening Ethernet switch.

3. Do you have two things assigning DHCP addresses on the same LAN segment?

4. Bad NIC card or connector.

 

After that it gets more difficult to troubleshoot:

5. Wrong driver for the Ethernet NIC.?

6. Out of memory condition preventing TCP from acquiring buffer space?

Hi please find my diagnostics. Thanks

I'm not an expert in reading diagnoistics, but it appears that your system has the br0 and br1 NIC interfaces

bonded together into a Link Aggregation Group (LAG).  Does the thing they connect to (Ethernet switch?)

support LAG and has that switch been configured for LAG?

 

You might want to try looking at your settings, and if bonded, eliminating the LAG bonding, then connect

just one of the interfaces to the Ethernet switch. The <your-servers-ip> /Dashboard/Settings/NetworkSettings page

is where you can re-configure the network settings.
