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(1000000.) a.shape=1000,1000 t0=time.time() b=numpy.dot(a.T,a) print "Elapsed time = ",time.time()-t0 reports an "Elapsed time" of 1.4 seconds under python 2.5 and 15 seconds under python 2.6 Same version of numpy, same machine, official numpy installers for windows (both with nosse flag) Are some libraries missing in the windows superpack for python 2.6? Perhaps the reported problem is already known, but I did not find any information about it.
