Result on my computer :

Test 1 (something is done by JScript)
    IE:                     Not Applicable
    FireFox:           30 > 160 (x5 or +130)
    Chrome:           5 > 60 (x10 or +55)
    Opera:              15 > 45 (x3 or +30)

Test 2 (nothing is done by JScript, just for comparaison)
    IE:                     Not Applicable
    FireFox:           30 > 80 (x3 or +50)
    Chrome:           5 > 40 (x8 or +35)
    Opera:              15 > 30 (x2 or +15)

There's cleary two factors that apply :
==> Time needed to move from managed C++ to unmanaged JScript
==> Time of JScript execution

These two factors are clearly dependant of the browser. 
In FireFox, it seems there's clearly a problem with that.
Others browsers react smartly enough.
