I like to use a max memory of 512M, but most examples (which have real-sized
data, see reference manual for numbers) run fine with far less memory (the
default of 64M is fine IIRC).

Planner holds about 2-4 solutions in memory (and in future versions this
might go up to 20-30 solutions), so that's peanuts. There is only 1
optimization algorithm, namely "Solution Tabu Search" which is activated
with "solutionTabu", usually set at a 1000, that uses more memory. But
almost all the examples do that and that's still no problem. Avoid that if
you really want to scale down memory.

Network bandwidth isn't used by Planner.
As for CPU: the more CPU speed, the better :) Do note that better algorithms
win versus more CPU any time. You can't solve planning problems by throwing
hardware at them.
