delayMicroseconds large overhead?

I am new to Galileo and Arduino - trying out the following code,

void loop()

{

  Serial.print(micros());

  Serial.print("\n");

  for(int i = 0; i < 10000; i ++){

      delayMicroseconds(10);

  }

  Serial.print(micros());

  Serial.print("\n");

}

It takes about 1.8 seconds to go through -  each delayMicroseconds takes about 180 microseconds to complete instead of 10 microseconds? How can I get better resolution here? Thanks!
