How do I use the stack from the EDK8.2i release specifically?
I'm using polled mode with a pretty small stack due to very little
memory (only on-chip memory).
My stack configuration looks like this:
pbuf_link_len 16
pbuf_pool_bufsize 1536
pbuf_pool_size 64
Regards,
Hampus

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?
