AS3 Optimization: Rectangle Vector Vs. 4 Integer Vectors

Speed Test:

I honestly thought the vector of rectangles would be faster
because I am only accessing using an index ONCE vs FOUR times.
And I know that cutting down on that with the use of a temp
variable has helped me speed up things in the past.

For example:
Something[i].x
Something[i].y

is slower than:
temp = something[i];
temp.x
temp.y

Maybe the four vectors are faster because I am using integers?
And the rectangle type uses number type?

Anyways: I ran 3 tests:
5 vs 43 milliseconds
8 vs 68 milliseconds
4 vs 35 milliseconds

import flash.geom.Rectangle;
import flash.utils.Timer;

var t1:int;
var t2:int;
var tt:int;
var g:int;

//rectangle in vectors:
var T:Vector. = new Vector.(10);
var L:Vector. = new Vector.(10);
var B:Vector. = new Vector.(10);
var R:Vector. = new Vector.(10);

//Vs:


//Rectangle:
var VEC:Vector. = new Vector.(0);


for(var i:int = 0; i<10; i++)
{
	var t:int = 1*i;
	var l:int = 2*i;
	var b:int = 3*i;
	var r:int = 4*i;
	
	//Make vectors:
	T[i] = t;
	L[i] = l;
	B[i] = b;
	R[i] = r;
	
	//Make rectangle:
	VEC[i] = new Rectangle(t,l,b,r);
}


var retNum:int = 12345;
var rec:Rectangle;
var n:int;
var temp:int;
