I use testcenter to test the performentance by using dpdk app testpmd on the platform of intel XEON E5-2650 v4 , it's a single socket platform.
The NIC is intel 82599 10GNIC with 2 ports.
The packet size is 64byte, and the testcenter uses two ports with 100%loading to transfer packets.
I think the intel platform has enough ability to transfer packet pattern (port1 to port2 and port2 to port1), but it still has frameloss.
When I use 2 10GNICs and each NIC I use one port，then using testcenter to transfer packet to the two ports, it almost hasn't frameloss .
So I don't know whether the NIC hasn't enough ability to transfer packet from NIC to PCIe path or the Intel platform hasn't enough ability to handle the packets from the two ports.
