What are the things I should tune ? Does having more no.of tx descriptors help ? With a burst size of 30 and having 512 tx descriptors , I get a speed of around one hundred thousand packets per second (74 byte packets). What are the ones that really affect the transmit rate ? I tried changing the burst size, but the speed decreased as I increased the burst size to some 500 (with 1024 tx descriptors). Thanks and regards....
