Giga what?
I’ve been testing my network speed again, trying to figure out why I’m not really seeing gigabit speeds.
I’ve eliminated the switches from being the problem as using a bit of crossover between two PC’s made no difference at all.
I think its a either a limitation of the RTL8169 cards or the PCI bus, as I tried from the Pentium4’s built-in Intel Pro 1000CT and speeds from iperf went up from about 67MB/s to about 82MB/s – although that was still to another RTL8169 PCI card on the other end.
