HI provintan,

I don't what speed can u reach (I haven't test it exactly yet), but I could suggest you some modifications:

- implementing rx procedure through interupt, instead with polling as is in the web server example.

- put interupt vector table in a TCM, along with interupt stack and interupt function

bye
