[K12OSN] A question about gigabit

[Les Mikesell]

Before doing that, I'd run cacti or one of the other bandwidth graphing
utilities for a while to see if you were even close to overloading
a single port.  I'd guess that you can't fill a single gig pipe
and the overhead of bonding would make things worse instead of
better (but you'd get failover for a bad wire or NIC, about the
least likely part to break).
