[SciPy-user] Speed differences in sqrt calculation: what is good to know

hi,

slightly off-topic, but still regarding the speed differences... what's 
the difference between the following 2 functions?

numpy.linalg.solve
scipy.linalg.solve

the first is almost 2 times faster on the same data (4096 repetitions of 
a A*a = b problem with A = 2x2 float32 matrix) - typically 0.30 vs. 0.57 
sec for the whole operation...

best,
