Obviously, I was hoping to get a faster python, but the size of the final binary is almost twice the size of the default Ubuntu version (5.2MB cf. 2.7MB), which I thought might cause a startup overhead that leads to slower execution times when running such a basic script.

Did you compare the actual code sizes? The size command can help you with that.

*** TEST SCRIPT *** $ cat ~/bin/timetest.py

RANGE = 10000 print "running {0}^2 = {1} for loop iterations".format( RANGE,RANGE**2 ) for i in xrange(RANGE): for j in xrange(RANGE): i * j

That's an extremely silly benchmark, unlikely to be representative of any actual Python workload. I suggest you try a less-trivial benchmark suite, such as: http://hg.python.org/benchmarks/
