[SOLVED] slow network transfers

[ppoludniak86]

good morning,

I have been trying to get my unraid server set up for the past few weeks. I have everything running what appears to be correctly, when I try to transfer media from my main windows machine to my unraid I am only getting 6 mb/s transfer. I have 10 gig ASUS cards in both machines that when running iperf show 6.84 gb/s transfer. when i switch to another windows machine on my network with standard gig connection it shows transfer of 46 mb/s. these are the steps i have done so far to try and track down my problem. I have switched out all my sata cables in the unraid box. changed all cables on network to cat 6, using cat 8 cables to connect to my 10 gig add on cards, precleared all disks before adding to array, parity is valid, running all necessary plugins, even though it may have been a bad sata controller on the motherboard and returned it for a different one. attached is my diognostic report and some photos showing iperf results any advice would be greatly appreciated.

I suspect that the transfers are running over the eth0 connection which is only running at 100Mbps according to your screen shots.

 

you probably want to reconfigure the network cards so that eth0 is the 10Gps ones to get what you want.

Check jumbo frame or try disable it.
