33 Mhz * 32 bits = 1 056 000 000 bits per tick,
1 056 000 000 / 10^6 (1 megahertz = 10^6 ticks per second) =
1 056 megabits per second
1 056 / 8 = 132 megabytes per second
It should actually be 100/3 Mhz.

May be good, but the bus is PCI only if I am not mistaken looking at
the spec. Not even PCI Express or PCI X, so it would be interesting to
see, but if you are concern about congestions with the Intel one, may
be this would be saturating the bus at 33MHz, or may be it might go at
66, but sure not 100 or 133 however. I saw some others, but none that
support PCI Express as a minimum however. So, I discarded them.
i haven't tested any 4 port nic's whatsoever yet, and don't know much
about these things, but isn't the theoretical throughput of the 33 MHz
32-bit pci bus around ~1 Gbit/s? so, assuming the system is dedicated
to routing, why would a theoretical maximum of ~0.4 Gbit/s be so hard to
handle, especially as most of it should stay on the internal pci bus of
the nic?
