Hi Tom, How do one calculate the theoretical limit of a 4x10G on a PCIe 3 x8 vs a PCIe 2 x8? Currently in our test server we have two 2x10G NICs on loopback with each other and I couldn't reach 4x10G throughput (total of 80G for both direction).
NIC 1 ----------------------------- NIC 2 port 0 <-------------------------> port 0 port 1 <-------------------------> port 1 Regards, BL.
