How can I measure the execution time of a Photoshop script?

[Cyril500]

I have several time-consuming Photoshop scripts and want to adjust them. Execution time is a measure of script efficiency for my goals. Hence, I want to measure the execution time of a Photoshop script.  Any help would be highly appreciated.

var totalTime = new TimeIt();

... do cool stuff ...

totalTime.stop();

// log it out

totalTime.getTime();

function TimeIt() {

  // member variables

  this.startTime = new Date();

  this.endTime = new Date();

  // member functions

  // reset the start time to now

  this.start = function () {

        this.startTime = new Date();

    }

  // reset the end time to now

  this.stop = function () {

        this.endTime = new Date();

    }

  // get the difference in milliseconds between start and stop

  this.getTime = function () {

        return (this.endTime.getTime() - this.startTime.getTime()) / 1000;

    }

  // get the current elapsed time from start to now, this sets the endTime

  this.getElapsed = function () {

        this.endTime = new Date(); return this.getTime();

    }

}

Thanks a lot for answering!!! But, sorry for misunderstanding!!! It was my fault when formulating the question! I need a script to measure the execution time of Photoshop Actions. Sorry!!!

Create a jsx file with the code above.

Replace this line:

... do cool stuff ...

whit this line:

doAction("ActionName", "ActionSetName");

replace the last line with:

alert(totalTime.getTime());

I suggest use high resolution timer or buil-in profiler in extend script toolkit.

$.hiresTimer

reading this timer get time of script execution and it also reset timer. So I suggest do first dummy reading for reseting timer at some point and second reading will show you how much time script spend since first reading.

Thank you for answering, but I am new to scripting hence I do not understand how and where to use    $.hiresTimer  to solve my issue in Photoshop...

[Jarda Bereza]

//reset timer
$.hiresTimer; 
//something you want measure
var a = app.activeDocument.artLayers.add(); 
var b = app.activeDocument.artLayers.add();
var c = app.activeDocument.artLayers.add();
//show message and read time
alert("Time: "+($.hiresTimer/1000000)+"s"); 
//reset timer beacause we don't want measure how long take click to "OK" button
$.hiresTimer; 
//something you want measure
a.remove()
b.remove()
c.remove()
//show message and read time
alert("Time: "+($.hiresTimer/1000000)+"s");

I want to measure the time of a Photoshop Action... like doAction("ActionName", "ActionSetName");

What strings should I use instead of

var a = app.activeDocument.artLayers.add();

and

a.remove()

Thank you very much for helping me!!!

There would be lines of code... something like you wrote. I don't know how to run recorded action.
