 I agree. The results are very surprising, and most likely wrong. It would 
mean that just changing it++ to ++it in a loop removes 80% of executed code 
from the loop. It can make things faster, but such big improvement is hard to 
believe.

 I suggest you repeat the test with exactly the same conditions for both of 
the variants (i.e. reboot, do the test; change to the other variant, reboot, 
do the test exactly the same way).
