++ I and -- I who have high efficiency?

++ I and -- I who have high efficiency?

When I see the blogs of experts, there is a question about the efficiency of ++ I and I for the loop (a little geek, but I like it ~)

Http://blog.csdn.net/dog250/article/details/5303375

 
# Include <stdio. h> int main (void) {int I = 0; for (I = 0; I <10; I ++) {printf ("Hello world! \ N ") ;}return 0 ;}
 

The main parts of disassembly are as follows:

# Include <stdio. h> int main (void) {int I = 0; for (I = 10; I> 0; -- I) {printf ("Hello world! \ N ") ;}return 0 ;}
 

Result of disassembly:

The efficiency of writing to I in the blog record of Wang Ran's predecessors is higher than that of I ++, but I feel no difference here...

Thank you for your advice.
