OT: PC Gigabit Through putQuestion PCI-32 theoretical maximum throughput would be: (((33 million cycles) * 32 bits) / 8 = 132 million bytes ) per second ...but since that's unattainable for more than a dozen ticks or so I'm guessing that 2/3 of that (88 million) is a more reasonable maximum. Meanwhile, I (think I) have heard that the rule-of-thumb for Enet overhead is something like: bitrate / 12 = bytes-per-second ...so for GigE we'd get: ~1,000,000,000 bits per second / 12 = ~83,333,333 ...which is in the same ballpark as that PCI guesstimate. _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/ _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
