Was that on Linux or Windows Alex?

I received my LC to LC OM3 fibre cable today, and the transceivers work, so I'm now running fibre between the server and switch.

I've moved the cards around, both in my X99 system and the server as the cards were in slots not able to fully utilise maximum speed, but it made no difference to my Iperf3 results. I  think it's a Windows thing, and may be also Iperf3, I found some talk of it having some problems on Windows. At some point I'll try Linux Live USB stick on the two desktop systems.

The motherboard on the server only has PCIe 2 slots (it is 10 years old), but as far as I can work out the x8 slot the NIC is in should be plenty fast enough. I'm considering changing the motherboard, and at some point installing Windows 10 Pro on there instead of WHS2011 which is now out of support.

I think I tested on both but to be safe I will assume Linux, the NAS I was testing against would always be Linux though.

I'm now hitting around 9Gbps between the two Windows 10 machines, but getting substantially lower to the server, between 4 to 6Gbps. This is with Jumbo Packets of 9014 bytes on all three machines.

The server is about 10 years old, running WHS2011 on an i3 540 CPU, but I don't see any increase in CPU usage during the tests. The NIC is a Supermicro AOC-STGN-I2S SFP+ which uses an Intel 82599 chipset. It's plugged into the x16 socket, but is a x8 card, socket is PCIe v2.

I'd definitely try booting the server from a Linux USB stick, just to confirm its not a hardware problem.

I've now tested with Linux Mint on the server and get slightly better results, but still no where near what it should be.

Actually this is all getting rather confusing, Iperf3 from the X99 to the server generally seems to be slower than from the X570 PC, and I've just discovered if I do -R -P2 from the X570 I can hit an average of 8.4Gbps and even 9.37Gbps, then another time it will barely manage 4.16Gbps, most odd.

I run a more windows optimised test, which equates to around 9Gbps  ;D
