Has
Xilinx (or anyone else for that matter) released a reference design with
LwIP tested to operate at some particular data rate on a given FPGA and
processor? That might help cut down on the chatter about how fast people
are getting LwIP to work with EDK based hardware designs with provided
cores.

-----Original Message-----Are you using the stack from the EDK8.2i release?I have seen TCP data rates of at least 50Mbps for the Interrupt mode of processing. What does your MSS file look like? What is your lwIP stack settings?

any difference at all.
Has anyone else noticed these differences in transfer rate?
