I can't make it fast(80sps) what is the matter?

[omnyx2]

I did 80 sps mode on hx711 however when I use code of example and make it as

void loop() {
  Serial.print("one reading:\t");
  Serial.println(scale.get_units(1)*1.1015, 1);
  // Serial.print("\t| average:\t");
  // Serial.println(scale.get_units(10)*1.1023, 1);

  // scale.power_down();			        // put the ADC in sleep mode
  delay(25);
  // scale.power_up();
}

it still shows me to maximun 10 min second? did I do something wrong?
