You should be able to get good speedup (factor > 1.8) on two nodes with
any reasonable interconnect (even 100 Mbyte ethernet) with PME. If you
are not getting that, it's worth trying to figure out why...the detailed
timings that come with Amber 7 often help, but it still can be a difficult
task....

This is over-optimistic for most problems, in my experience. The final
sander code is now frozen, and we will post benchmarks soon, probably next
week.
