How is it possible to get "11-12Mbytes/s" from 10Base2? Redo your math ( 2(20) * 10 / 8 ) and you get an absolute of 1.31MB/s for 10Mbit Ethernet. BUT this number has no meaning in the real world! The theoretical maximum data throughput for a 10Mbps Ethernet system is 9.744MB/s using 1518 byte frames. The last time I checked Microsoft could only break anti-trust laws, not physics.
