Preloader does not show until load is at 71%

Hi I have a simple preloader, but not matter how many times I test it, on different platforms and different speeds… the screen remains blank until it gets to 71%… is there anyway to get the proloader to show earlier?

Frame 1 AS
bytes_loaded = Math.round(this.getBytesLoaded());
bytes_total = Math.round(this.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
this.loadBar._width = getPercent574;
this.loadText = Math.round(getPercent100)+"%";
if (bytes_loaded == bytes_total) {
this.gotoAndPlay(5);
}

Frame 2 AS
this.gotoAndPlay(1);
