In most cases (all?) I have seen did the performance not differ when 
between running python scripts in 32 or 64 bit env.
But that is not true for compiled code.
Just take your script and do some benchmarking.

In germany we say: probieren geht über studieren.
Don't study - try it.

An ex-post explanation will show at hand, I promise :-)
