The attached image shows what I get with Python 2.3.5, Enthought Edition 
(0.9.7) on windows XP laptop.  Weave.blitz appears to behave fine 
showing a consistent and significant benefit.

It doesn't appear to affect this problem because the arrays are so 
large, but blitz does some checking to make sure the array sizes are all 
compatible before running calculations.  This can be significant in some 
cases.  You can try the following and see if it helps (but I doubt that 
is the issue).
