[mdlug] Maxing out on 10/100 LAN

[Robert Adkins II]

That is along the lines I was thinking, unfortunately, to go to GB ethernet,
I do believe that I will need to rewire the whole building and I am unsure
if that will really fundamentally change performance across the whole
network. I certainly would need to acquire almost 30 Gigabyte Ethernet
cards.

Perhaps I will dig around and setup samba to serve the same shares all off a
series of network interfaces.

Thanks.
