My machine is not exactly an 8500r. It's an Intel pre-release
engineering sample (8-way 900MHz PIII) box that is similar to an
8500r... there are some differences when going across the choerency
filter (the bus that ties the two 4-way "halves" of the machine
together). Bill Hartner has a test program that illustrates the
differences-- but more on that later.
I've got 4 PCI busses, two 33 MHz, and two 66MHz, all 64-bit.
I'm configured as follows:
PCI Bus 0 eth1 --- 3 clients
33 MHz eth2 --- Not in use
PCI Bus 1 eth3 --- 2 clients
33 MHz eth4 --- Not in use
PCI Bus 3 eth5 --- 6 clients
66 MHz eth6 --- Not in use
PCI Bus 4 eth7 --- 6 clients
66 MHz eth8 --- Not in use

2900 simultaneous connections, each at ~320 kbps translates to
928000 kbps, which is slightly less than the full bandwidth of a
single e1000. We're spreading that over 4 adapters, and 4 busses.
