While I was testing with the L2 Forwarding (sending pingpong packets from client to server(L2 fwd)) I wasn't able to get a good result when I increased my packet size to 2048. Of course I have changed the default size of the RTE-BUF and the pools for each client and server before increasing the size of the packets. Does this problem have to do with the NIC architecture? If so, is there a document to find out the correct limit size for the packets? Thank you for reading this letter Sungho Hong
