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). > > I've measured 94.87 Mbps myself on full duplex 100BaseTX (back to back > > with a crossover cable or through a switch).

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 :-) Steinar Haug, Nethelp consulting, sth...@nethelp.no To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-hackers" in the body of the message
