Tuning GigE network for cluster computing?

First, I'm running FreeBSD 6.1-stable on a small cluster
with 6 nodes that contain Tyan motheriboards. These broads
have Broadcom GigE NICs that use the bge device.

The cluster will be using MPI to possibly shove large data
sets through a GigE switch, so I'm trying to determine how
best to optimize the transfer.

Would DEVICE_POLLING and/or jumbo frames likely methods for
enhanced speeds?
