[Wrfems] RAM Requirements

[Robert Rozumalski]

Hello Ben,

You're thinking about this too much. If you are concerned about the
amount of memory on the machine then buy more.

1Gb per core should be more than enough for most domains unless you
have multiple nests, in which case the bigger limitation is your
CPU speed.
