I looked it up last night. According to the always reliable
Wikipedia, PCI-X brings the bus clock to 133 MHz. Still 64-bit. So

A lot of what Maddog wrote pertains more to coax or hub based Ethernet
(CSMA/CD, Carrier Sense, Multiple Access with Collision Deterction) which is
true Ethernet. Twisted pair media used with switches and routers I
believe is all Single Access and has no collisions.
If I remember correctly,
There are still collisions (of a sort) even on full-duplex switched
networks. Two 10 Mbit devices can't talk full speed to the same 10
Mbit conversation partner, obviously. Store-and-forward switches and
routers help with short-term congestion, but even without 2-to-1
bottlenecks, most switches
I have a cheap gigabit nic ($20) in my system and suspect it is slowing down
throughput so I'd like to upgrade it.
I did the google linux thing. Half were error reports, half were from
2004, half were sales reviews, etc (yeah, that 100%). The Linux HOWTOs
are 2004 and earlier so there's
Now that Intel has released the HW specs for the
e1000 family (generally having 825nn part numbers)
I can recommend it. The driver is mature and in
wide use and offers full support for useful features
like bonding, ipv6 and huge packets. Esoterica:
it even has a (compile time) option that
answers for that stuff?

I'm not the best with these bit/byte problems so I might be wrong,

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)

I thought I read somewhere gig ether should be on the motherboard, not PCI.
Many modern motherboards do include one or more gig Ether ports.
Sometimes, these
PCI-32 theoretical maximum throughput would be:

...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
