I'm working on something similar.  Not Gigabit Ethernet, but a gigabit
rate network.  lwIP in it's current form isn't targetted at this, and so
is unlikely to give the performance you require.  This will be especially
true if you use the sockets interface as the amount of thread switching
and message passing is just too great an overhead.  I'm creating a
somewhat different version for which the path for normal data delivery and
transmission is in a single thread, and which isn't so concerned about low
memory usage.  This should improve things.
