Comment(by pcapriotti):
I do see a small difference when compiling with `-prof`, though much less
than you reported (5.69s vs. 4.89s with 1000000000 as argument).
Can you please post the prof files for runs with 1000000000 as argument?
Can you also check if the difference goes away when you compile the sample
program without `-prof`?
