quickly)?
My Athlon XP 2400+ can do more than 2000Mbit/sec, when I do
dd if=/dev/zero of=/dev/null bs=1m count=1000
Maybe u want to try the same on ur "patient"?
The main thing to look out for is the pci-bus.
A normal 33mhz/64bits pci bus can only do about
100 megabyte, if storage and and network are both
connected to this bus contention will happen.
(70mb ide, and 500mbit network just won't fit)
i have ~50mbit traffic on fxp0 x2 disk read = 100Mbit
and currently have ~200-250mbit on em0 x 2 disk write = 400-500Mbit
so 500Mbit total with disk r/w..
both network cards and all disks are in pci slot (33mhz/32bit)
