12.5 Mbytes/sec on the wire *is* 94.93 Megabits/sec application to
application using TCP - that's what I'm trying to say. You'll never see
12.5 Mbytes/sec application to application - look up the Ethernet frame
formats to see why (1460 bytes of TCP payload is 1538 bytes on the wire).

94.87 Mbps, application to application, using ttcp. Using Mega = 1000000,
that should be 11.86 MBytes/sec.

Oh yeah, this was measured with FreeBSD, with a P-133 on the receving end,
back in '96 :-)
