March 22, 20242 yr 2.5gbe Nic (unraid) -> 2.5gbe switch -> 2.5gbe Nic (Windows) It looks like i am only get 2.5gb up to the server, and not down testing from SSD to SSD both with Iperf 3 testing and copying a large file shows the same. diags attached, i don't know what i'm doing wrong Edit: Updated to 6.12.8, installed the community driver, tried disabling bridging - no change urserver-diagnostics-20240322-1943.zip Edited March 23, 20242 yr by TheBuz

I've tested the switch (same port) and cables on another 2.5 device and got full speed. the Unraid NIC Is receiving 2.5 fine, and capping out at 1gb sending, i can't see that many settings to change in Unraid, and i've tried the community drivers here
March 23, 20242 yr Author Tested with a USB 2.5gb NIC, (which was also tested ok on another machine) same behavior - 2gbs up to the server (inbound) -- 1gbs down. This looks like an Unraid issue... Edited March 23, 20242 yr by TheBuz
March 23, 20242 yr Community Expert Solution Can only tell that it's not a general issue, since many users, including myself, can get 2.5GbE in both directions.
March 23, 20242 yr Author Sorry for wasting your time turns out it was the NIC on my testing PC. The ethernet cable is routed from the PC to the right of the room, moved it to the left to test on another PC all working fine, move it back to the right, to connect to the unraid server, get issues. Must but a loose connection in my NIC the weight of the cable when it goes to the right is enough to make it run slow. URGH. Not only that, iperf is wildly off, Test with iperf on other machines still hitting that 1gbps wall, but it I do a basic file transfer to or from windows to or from the server, it's full speed. That's not what's happening in iperf URGH again Thank you for your patience. That was a pain to diagnose
