Hi i have a weird problem. i have 2 nic in my unraid server, a normal 1gbps (onboard) and a 10 gbe nic (Intel Corporation 82599ES 10-Gigabit SFI/SFP+) if i try an iperf from my computer to my server (iperf3 -s and iperf -c) i got only 1gbps i disable docker and vm services to go in the network config, i change mtu to 4088, and try an iperf and now i get my speed [ 4] 6.01-7.00 sec 126 MBytes 1.07 Gbits/sec [ 6] 6.01-7.00 sec 126 MBytes 1.07 Gbits/sec [ 8] 6.01-7.00 sec 126 MBytes 1.07 Gbits/sec [ 10] 6.01-7.00 sec 126 MBytes 1.07 Gbits/sec [ 12] 6.01-7.00 sec 126 MBytes 1.07 Gbits/sec [ 14] 6.01-7.00 sec 126 MBytes 1.07 Gbits/sec [SUM] 6.01-7.00 sec 758 MBytes 6.39 Gbits/sec and now, i start my vm services, and i still get my bandwidth if i try to start docker services, everything slowdown a 1gbps.
