Scott,
Jumbo frames will be required by all clients and servers on the network. It was
a Sun Professional services engagement to set it up, not sure if that has
changed. The Sol 10 Stack has improved efficiency so for a given speed there is
less CPU used. The network may not run any faster but the CPU utilization will
go down over Sol9.
