You can make Python about 2x faster with these changes:
values = [value % maxInt for value in xrange(warmUpIterations)]
values = [(value, value * 2, value + 1) for value in values]
map_get = map.get
# for i in xrange(warmUpIterations):
# num1 = i % maxInt
# num2 = num1 * 2
# num3 = num1 + 1
for num1, num2, num3 in values:
map[num1] = num2
value = map_get(num3)
# if value:
# # Make sure we do something with the result so that it is not optimized away
# sum += value
What changed:
map.get
with map_get
to avoid the method lookup.Let me know if u have clear understanding of why this would be so.
