[Numpy-discussion] speed degression

Hi,

Some of my code is heavily using large complex arrays, and I noticed a speed
degression in NumPy 1.0b2 with respect to Numarray. The following code snippet
is an example that on my computer runs 10% faster in Numarray than in NumPy.

>>> A = zeros(1000000, complex)
>>> for k in range(1000):
...        A *= zeros(1000000, complex)

(I replaced 'complex' with 'Complex' in Numarray).  Can anyone confirm this? 

Ciao,
Joris
