here it's a 486 80MHz overdrive (yeah:) with 32mb RAM doing iptables(nat) + bind9 + dhcpd serving a 512/128 cable connection to 10 pc's load average: 0.07, 0.03, 0.01 I would be realy carefull with services like snort and co. they can bring these babies to there knees quite easy. but everything in kernel-space (as iptables) runs real smooth. but now back to topic I don't have any experience with gigabit ethernet but would expect the same kernel- vs. user-space differences - just on an higher scale. On a *real* high scale to be precise - so expect surprises. horror stories anyone ? As somebody else mentioned the system bus will be limiting so you can't put a gigabit ethernet in *all* the pci-slots of a motherboard and expect it to run at full speed. What would be the maximum of gigabit cards you can add to a regular scale motherboard? (recent technologie and good quality) Could somebody explain if a 32bit PCI-bus is generally fast enough for a gigabit-card. Do you realy need 64bit. On my level of using networking I have a usb-ethernet adapter claiming to be 10/100mbit. Because of the version 1.1 usb-bus it will never be faster then 11-12mbit. Any similarities with 32bit-PCI and gigabit-ethernet here ? sorry for bringing up new questions - but these look like the stuff the OP wanted to know. gruss pascal
