Re: ncl performance

IMHO ... memory is always good to have ...

Often mhz are emphasized ... not that important in and of
itself. Overlooked issues are data movement from memory and cache.

You can have lots of memory and a fast cpu but if the data
movement is slow then the code will run slowly. I do not
just mean reading from memory ... writing takes time also.
If you have intertwined read/write tasks then performance
could be even slower.
