For those that are busy telling me in private mail that PCI is only
133Mbytes per second, please note BITS versus BYTES.
OC-3 = 155Mbit (or about 20MBytes/sec if you like)
PCI = 1.xGBit (or about 133MBytes/sec)
I am well aware that OC-12 is faster than PCI, but it isn't faster
than the fast 64 bit PCI stuff, which clocks in at 533MBytes/second,
or something on the order of 4.25 Gbit/sec.
(Yes, I know my math is somewhat off, but I don't have a calculator --
thats approximating off the top of my head).
Anyway, PCI is more than fast enough for OC-3 stuff.
