Scroll down past the copyright, license and attribution. Read the
38-line comment that explains just how crappy this chip really is.
Well - really "low end".
But - this computer can do memcpy at 80MB/s, so at 3.5MB/s it should be 5%
CPU for memcpy, and one interrupt per one packet (2500 packets/s).
Is something more that make it consume >50% CPU?
