A word of advice

    Hooking into the ‘all’ action in WordPress (which this plugin does) has a serious performance hit. It will skew the elapsed processing times due to the increased overhead of using this hook.

    Therefore, you should take the reported function execution times as little more than guidelines to help you quickly spot poorly performing functions. The actual reported execution times will not be reliable.
