Re: Recommended PCI gigabit ethernet card? OT: PC Gigabit Through put Question

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

I'm not the best with these bit/byte problems so I might be wrong, but. A PCI bus can pass 1056 bits a second (32 bit, 33 mhz) tcp/ip over head is somewhere around %20 (1056 * .8 = 844.8) What can you reasonably expect a pci gigabit card to give you for through put? PCI Buses are generally
