Your figures sound very wrong. I routinely get close to 1 MBytes/s UDP transfer (using a 1c20 full featured design). You will also see in the MicroC/OS-II forum that someone has got throughput of 4Mbytes/s.

I&#39;m afraid this is not a case of a simplified port over performance. It&#39;s mostly down to the performance of the lan91c111 interface.

Useful things to boost performance are to raise the fMax and increase the size of the data cache.

That said though your figures sound low.
