Yeah I plugged the "new" hardware directly into the same cables. However, I've tried multiple switch ports.

So, I'm chasing some sort of mythical evil here. This isn't worth troubleshooting anymore. I moved my desktop workstation (which hits 800MB/s with ease) down to the rack mount workstation (the one stuck at 400MB/s) and now the hardware from my desktop workstation is stuck at 400MB/s. Just by...

Yes I'm on the latest BIOS. I don't see any bifurcation settings in the BIOS. Not sure its supported on this board.

I've tried several cards. My X8 system seems to be my fastest....

This returns nothing. It's an X11 system with gen 6 Xeon so it's not what I would call "legacy".

So I just used an Ubuntu live image and got essentially the same results. The iperf3 results shows between 1G to 4G connection. The file copy in the linux live image was actually stuck around 250MB/s.

Yeah now you see why I've been racking my brain over this for months... lol. None of it makes any sense. The "turn this device off to save power" was checked. I unchecked it and the iperf3 results actually went up to 2G speeds but the file copy is still stuck at 400MB/s. I should note I've seen...

And this is the connection state:

There is an onboard 1G NIC but its not connected.

Here is a screen shot from one of the Windows machines. I regularly copy files from this workstation to the TrueNAS server at 700-800MB/s.

iperf3 -s iperf3 -c remotehost -i 1 -t 30 Just the default commands from the documentation. I've done Windows to TrueNAS and TrueNAS to Windows with 3 different Windows machines and 2 different TrueNAS servers. Actual file copies between all of those machines (except the problem child) hits...

I tried iperf3 to and from multiple machines and they all max out at about 100MB/s.... I'm using the default settings... Even on my main workstation where I'm getting 800+MB/s.

Its a single port. I've tried with a dual port x520 and and dual port AOC-STGN. I currently have the NIC in a x8 CPU PCIe slot and the nvme in a x4 PCH PCIe slot. There shouldn't be any PCIe bottlenecks.

So I removed the 9341-8i so the nvme and AOC-STGN were the only PCIe devices. The NIC only needs 2 channels to reach 10G and the nvme needs 3~4 channels to reach its max speed. The PCIe to NVME adapter only has 4 pcie lanes. What's killing me here is that I have another machine with the same...

I don't have a GPU but I have a 9341-8i installed. All components were tested independently. I've tested with a Sabrent 1TB Rocket NVMe and a Samsung 970 PRO SSD 512GB both of which test well over 2000MB/s read and write. I swapped the NIC into the other workstation to make sure it was capable...
