ggaoed for example can handle multiple interfaces in the configuration and
is designed to deliver highest performance with for example automatically
load balancing over several NICs.
If you want to use vblade you might be better off using bonding because
vblade cannot handle several interfaces in one instance. You'll get another
performance penalty when using several instances of vblade listening on
different interfaces.
I am not sure if LACP enhances performance in your case: I think from one
server to the other you will only get 1GBit; for LACP to work as expected
you need many-to-many or many-to-one connections. All pakets belonging to a
connection will use the same wire. This article has some
details: http://serverfault.com/questions/8512/multiplexed-1-gbps-ethernet
also Wikipedia has some information on this.
Another thing is that you loose the ability of having a redundancy in the
switching backend.
