John,
For the command-line selection mechanism of numerix.py to work, the following change is needed:
if which[0] is None: ## Add this line
which = rcParams['numerix'], "rc"
Otherwise, the rcParams value clobbers the command-line value.
Update on pcolor_demo2.py: strange things are going on, but now, using profile.py, I get 2.72 seconds with Numeric and 9.49 seconds with numarray. I don't have any explanation for why it was taking 80 seconds with numarray when I tried it earlier today. It is still much slower than with Numeric, though, which seems odd.

Numarray will be slower on "smaller" operations, in particular
if one is manipulating many small arrays, or looping over many
indiviual array element accesses. I haven't profiled it but
I'm guessing the difference lies in the list comprehension that
calculates the vertices which is doing many array indexings.
