clearMarks	Removes marks and their associated time values.
clearMeasures	Removes measures and their associated values.
clearResourceTimings	Clears the current list of saved PerformanceEntry objects, if any.
getEntries	Returns an array of PerformanceEntry objects that report a series of recorded events in chronological order, based on startTime.
getEntriesByName	Returns an array of selected PerformanceEntry objects in chronological order, based on startTime.
getEntriesByType	Returns an array of selected PerformanceEntry objects in chronological order, based on startTime.
getMarks	Returns performance marks and their associated timing values.
getMeasures	Returns performance measures and their associated duration values.
mark	Records a performance mark, which is a time value associated with a name.
measure	Records a performance measure, which is the duration of time between two performance marks.
msWriteProfilerMark	Writes a profiling event.
now	Returns the number of milliseconds, accurate to a thousandth of a millisecond, from the start of document navigation to the time the now method was called.
requestAnimationFrame	Registers a function to call when the system is ready to update (repaint) the display.
