On a relatively slow machine like t PC, or even an AT, a smart
 Ethernet board can make
a big difference in performance.  I know someone who claimed that at Calma
they measured a 10-to-1 difference in sustained throughput in file 
transfer between a dumb and a smart card.

Another factor, however, is the the size of the buffer in the Ethernet card.
If the buffer is too small, it will miss packets if the sending system can go
at a faster rate than the PC.  (That just about defines the universe-)-) )
