Please show your code.  There are several factors that have changed 
here.   For example,  Python 2.4 is different that Python 2.3. 

There are only a few usages when Numeric is faster than NumPy and in 
most of these using regular Python lists is faster than Numeric and 
NumPy anyway. 

Nonetheless, there are still improvements that can be made to NumPy.  
Which version of NumPy are you using?
