Peter - Try for gigabit ethernet with Jumbo Frames for optimal throughput.

For most data in fewest packets, then compressed data is the thing,
either having previously been compressed on the client or per TSM
compression at send time.

There is also Adaptive Differencing (a.k.a "adaptive sub-file backup"),
which may be applicable, which reduces transmission requirements.
