I don't understand, how it is possible... The simplest solution works for 0.015 sec.

How do you read and write?

scanf("%d%d", &a, &b);
printf("%d\n", a + b);


and streamed input doesn't give any increase in speed

Can you explain me how to read and write for 0.001 sec?
Do you use buffer input?

Probably 15 ms is a minimum tick of OS (mb Windows). Thus the program
#include <windows.h>
#include <stdio.h>
int main()
{
 Sleep(0);

 return EXIT_SUCCESS;
}

will work 15 ms while it will be not replaced by any another (as a result of actions of the dispatcher). Including the program for measurement of execution time.
Someone can bypass this restriction.
