RE: [lwip-users] A speed question

[Matthew Yingling]

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.

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?

I updated to the 8.2i release of EDK but unfortunately I didn't notice
any difference at all.

Has anyone else noticed these differences in transfer rate?
