For those following network performance issues,

As networks have progressed in speed from 10Megabit to 10Gigabit, the 
size of the transmission unit has stayed the same.  This fact impacts 
the performance of networks.  The following link is a very useful 
starting point on Jumbo-frames and larger Maximum Transmission Units.

Matt Mathis of the Pittsburgh SuperComputing Center is one of the 
leading investigators into larger packet sizes and their impact on 
performance.  He is also one of the co-authors of a new Request for 
Comment (RFC) regarding path MTU discovery, the ability for end machines 
to discover the maximum transmission unit.
