I am new to 10GB game but I am getting extremely slow speeds on my 10GB network, 135-170 MB/sec using iperf3, between my desktop computer and my FreeNas box. I just added the 10GB cards: (1) Chelsio T520-CR in my FreeNAS Mini running FreeNAS-11.3-U4.1 and (2) Intel X540-T2 running the lastest intel driver 220.127.116.11 on a home built Desktop computer running Windows 10 Build 1904.
I am using the SPF+ ports on my UniFi Gen2 switch to connect the devices.
Any help would be greatly appreciated!!
