Hi Michael, > What can I do to trace down this problem?
May I suggest that you try to be more selective in the core masks on the command line. The test app may choose some cores from "other" CPU sockets. Only enable cores of the one socket to which the NIC is attached. > It seems very similar to a > thread on this list back in May titled "Best example for showing > throughput?" where no resolution was ever mentioned in the thread. After re-reading *that* thread, it appears that their problem may have been trying to achieve ~40 Gbits/s of bandwidth (2 ports x 10 Gb Rx + 2 ports x 10 Gb Tx), plus overhead, over a typical dual-port NIC whose total bus bandwidth is a maximum of 32 Gbits/s (PCI express 2.1 x8). -- Regards, Robert
