var ajaxdecay = 2; //  1  	Determines the progressive slowdown in a Ajax.PeriodicalUpdater object refresh rate when the received response is the same as the last one. For example, if you use 2, after one of the refreshes produces the same result as the previous one, the object will wait twice as much time for the next refresh. If it repeats again, the object will wait four times as much, and so on. Leave it undefined or use 1 to avoid the slowdown.
