Transfer file speed crashed, with no system or UnRaid changes

Hi Everyone,

I all of a sudden had a file transfer speed drop from 112Mb/s and now is down to 10Mb/s with no changes to my system.

No power issues as is on a UPS, with no log errors. My other 2x Towers are running at full speed transfers with no slow downs on the same UPS..

Am running 6.7.2.

Diagnostic was taken when a file was transfered to disk 11. 

Transfer to any disk is exactly the same speed reduction.


I have powered down the Tower3, unplugged, reset the entire network switches and modem.


Attached a diagnostic file.

Appreciate any help or advice.

There are no writes to any disk when the diags were saved, maybe it was still being cached to RAM, you can do a network test with iperf.

Thanks Johnnie, I tried to run iperf but following SpaceInvaderOne video I could not install.
I really am not a linux command person, sorry.


Will try to get a speed for you. Searching now for info 

All 3x of my Towers sit on the same UPS, and same network switch, right next to each other. is weird.


Much appreciated

Both Tower 2 and 3 are exactly the same motherboard, cpu. Ram is 32Gb Tower3, 16Gb in Tower2

So I changed the network cable, port on the 8 port network switch.
Changed the network switch still the same speed.


Tomorrow will try a pci-e network card and see what changes
