Honored ContributorMy tests show the same. Talks that I have had with various people indicate that this is in part due to system throughput (DMA isn't used for the smsc lan chip), so I would expect some improvement with increased clock. Additionally in what little time I have spent looking at the kernal code, I seem to remember the MorethanIP driver using DMA so you may get more mileage from that solution. You could get one of the Microtronix uKits and test both.
As far as why... in my case we need to be very power consumption wary and implementing a Altera solution is much more power friendly.
