Sending 10,000 packets for the test. First 500 packets are not used in the stats. We are using another RTOS on PC and the RTOS uses an Ethernet card which the Windows does not "see". Wireshark media specific capturing does not list the RTOS we use, but will try.

Incidentally, the Ref. design binaries for "Accelerating Ethernet Performance", when run on Stratix-II Nios-II development board shows roundtrip time of under a millisecond. The design does have number of optimization, including checksum in hardware. The document is old as the board is not supported anymore, but pointers do help nevertheless.

thanks,
