Re: 1 or more network cards

["junkyjunk.com" <debian@junkyjunk.com>]

At 10Mbps, having a few ethernet cards will speed up your transfers, but 
it woud be easier to use 100Mbps instead. If your upstream is only 
10Mbps, and you're pushing 10Mbps, having multiple ethernet cards won't 
help too much.

If you were really wanting to use more than one card, I would suggest 
reading the "ifenslave" man page. ifenslave will allow you to bind two 
or more ethernet cards together with the same ip address, effectively 
doubling your data rate.
