To John:
Did you try larger arrays/tuples? I would guess that makes a significant
difference.
No I didn't, due to the fact that these values are coordinates in 3D (x,y,z).
In fact I work with a list/array/tuple of arrays with 10 to 1M of elements
or more.
What I need to do is to calculate

Hi,
Spatial hashes are the common solution.
Another common optimization is using the distance squared for
collision detection. Since you do not need the expensive sqrt for
this calc.

Hi,
There are some discussions on the speed of numpy compared to Numeric in this
list, however I have a topic
I don't understand in detail, maybe someone can enlighten me...
I use python 2.6 on a SuSE installation and test this:
#Python 2.6 (r26:66714, Mar 30 2010, 00:29:28)
#[GCC 4.3.2
