This depends entirely on what the two NICs are connected to. If you have
them just plugged into a shared ethernet segment, then you'll see no benefit
really. If you have them plugged into two ports of a switch, then you could
conceivably see some benefit, although you will have problems with peer
caches if they are configured with you as a peer and you receive traffic on
one IP and send on another (and the two IPs don't resolve to the same
hostname).

This is remarkably like the discussion of load balancing traffic going on in
another thread on this list. Check the archives if you've not already seen
it.

Cheers,

Chris
