Optimize Script

Anyone have any tips on optimizing this script? I heard that it’s quicker to use int() than math.round???

[AS]
txtArr = [“null”, “null”, “null”, “null”, “null”, “null”, “null”, “null”, “null”, “null”, “null”];
urlArr = [“domain1.com”, “domain2.com”, “domain3.com”, “domain4.com”, “domain5.com”, “domain6.com”, “domain7.com”, “domain8.com”, “domain9.com”, “domain10.com”, “domain11.com”];
// -----------------------------------
for (i=0; i<txtArr.length; ++i) {
bu = root.sectionMC_05[“link”+(i+1)];
bu.whichTxt = txtArr*;
bu.onRollOver = function() {
attachMovie ("dragShopMc
"+this._name, “dragShopMc”, 1, {_x:_xmouse-95, _y:_ymouse+151});
dragShopMc.onEnterFrame = function (){
this._x = _xmouse-Math.round(this._width/2);
this._y = _ymouse+Math.round(this._height);
}
_root.sectionMC_05.dragShopMc.text = this.whichTxt;
};
bu.onRollOut = function() {
dragShopMc.gotoAndStop(1);
dragShopMc.removeMovieClip();
};
bu.onDragOut = function() {
dragShopMc.gotoAndStop(1);
dragShopMc.removeMovieClip();
};
bu.onDragOver = function() {
dragShopMc.gotoAndStop(1);
dragShopMc.removeMovieClip();
};
bu.onPress = function() {
dragShopMc.gotoAndStop(1);
};
bu.link = “http://”+urlArr*;
bu.onRelease = function() {
getURL(this.link, “_blank”);
};
}
