Hello everyone, I have recently established two servers using Unraid, one with 3 314A network cards and the other with 2 flr544+ network cards. I connected them all to Mellanox sx6036. As each network card has two 40G interfaces, I expected to achieve high speed through LACP. When I finished configuring it, I used the built-in iperf3 to measure the speed and found that all interfaces except eth0 had no load, so it could only run around 25G. I hope to get help. This is my configuration picture (the machine equipped with 314A currently only has two ports inserted)

Iperf3 test in multiple session ?  if single session, then traffic will happen in one link only. ( Even multiple session, I am not sure does traffic will balance on different interface, because they are same source-destination mac address )

Sorry everyone, I currently need to move the equipment to a new studio, so it will take about half a month to try the solution you mentioned. After the move is completed, I will test it one by one. Thank you for your solution

Yeah, keep that in mind, same for SMB transfers, a single transfer will only use one NIC, LACP only helps with multiple transfers.
