fwiw, here's the timings I get on a slow windows box (using
PythonWare builds, and time.clock() instead of os.times()):
python 1.5: 2.01
python 2.0: 3.02
python 2.1: 3.00
python 2.2: 3.04
after playing some more, I ended up with this little benchmark:
def dosomething(item):
return [None, None, None]
data = [None] * 100000
import time
t1 = time.clock();
x = map(dosomething, data)
t2 = time.clock()
print t2 - t1
python 1.5: 1.02 seconds
python 2.0: 1.95 seconds
python 2.1: 1.85 seconds
python 2.2: 1.90 seconds
