Hello,

 

Im running my server with integrated 1Gb networking card + pciE 10Gb Mellanox SFP+ Card.

 

I have switched the eth0 and eth1 to have the 10Gb Card as primary for all my bridges.

I'm getting some weird behaiviour :

 

First : Iperf

- doing an Iperf to my Unifi UDM Pro, I'm getting about 5.5Gb

- but doing the Iperf from the UDM Pro to the server, I'm getting only 2 Gbp of speed

The network and the switch are not the Issue, I have an old Thecus N7700 NAS running xpenology with the same 10Gb card inside, and I getting an Iperf of 7Gbp in both directions.

 

Second running Speedtest

- when running a speedtest CLI on the Unraid server, I'm only getting 1Gbps, it seems that speedtest tries only to use the 1Gb Card. When unplugging the cable, the speedtest does not work.

- running the Speedtest on the UDM Pro, I'm Getting 7Gb down and 6 Gb up.

- running the speedtest on the xpenology, Im getting 5Gb down and 4.5Gp up

 

All the core Unraid server internet functions ( coomunity apps for example) are not working when unplugging the 1Gb Card. So Unraid does not have internet access when unplugging the 1Gb Card. But the VM and Docker that are running over a Bridge/Vlan are geetting about 2Gb of speed

 

there are no Bond Setup and Bridging is activated.

 

The question are the following :

- How to switch the connection to the 10Gb Card

- How to improve the networking Speed ?

 

The Unraid server is running an Asus Motherboard x570 Pro with an AMD Ryzen 5 3600 Processor and 64G of Ram

Whatever it is good for, your eth0 has multiple (30,40,50) VLANS assigned.

So, check your VLANs and remember "less is more"

 

Else the general hint applies: wait!

If you switch over to a different card (mac address) it may take up to an hour until all devices in the lan recognise the new mac address.

 

Keep eth1 disabled or unplug it and wait...

It has been a few days now .....

 

I have not disabled the NIC in the Bios, may be this is the solution, I will try when coming back from business trip

The ARC cache only lasts for an hour... but of course, if you switch back and forth all the time, the hour restarts with every switching...

 

So, I tried deactivating the Internal 1Gb Nic and now I'm getting speedtest values about 5Gb/s down and up on Unraid

 

But in docker and VM, I do not get over 1.5Gb/s. Is there a way to tweak this ?

No idea, thats a different issue. I'm out here

 

thanks for your support,

 

frustrating that a low hardware over 15years old ( Thecus N7700 ) running xpenology is using the full speed of capable network and the unraid server with descent hardware and recent and with a paid licence does not support this .....
