This is a pretty common general observation. Details depend on the types of
processors you have, and on the interconnect between nodes. If you use
gigabit ethernet as an interconnect, you are pretty much limited to running
jobs on one node.
Be sure to try pmemd, if it's feature set meets your needs. It should be
faster than sander under almost all job conditions.
