Hello,
I have found performance problems under windows when using python 2.6
In my case, they seem to be related to the dot product.
The following simple script:
import numpy
import time
a=numpy.arange(100.)
a.shape=1000,1000
t0=time.time()
b=numpy.dot(a.T,a)
print Elapsed time =

Hello,
It seems to point towards a packaging problem.
In python 2.5, I can do:
import numpy.core._dotblas as dotblas
dotblas.__file__
and I get:
C:\\Python25\\lib\\site-packages\\numpy\\core\\_dotblas.pyd
In python 2.6:
import numpy.core._dotblas as dotblas
...
ImportError: No module named

reports an Elapsed time of 1.4 seconds under python 2.5 and 15 seconds
under python 2.6
My computer reports 0.34 seconds
