Website loading time programmatically

Question

Hello,

I'm looking for a solution on monitoring website loading time Programmatically I build my web application on Codeigniter and can use the benchmark class for getting the server site execution time but what I need is the total loading time of a website from the time a server-side call is done until all the contents of the website have been loaded. I'm currently using a JavaScript function that subtracts the time before and after the onload event but I'm not sure about the accuracy of this method.

Please note that I'm not interested in "Best Practices" and recommendations for improving speed like those offered by Google speed, YSlow, etc

Is their any client-side library or something that I could reuse for accurate loading time, similar to those provided by the Google Chrome developer tools that provide loading time for images, scripts, etc?

Answer 1

The answer is no I'm afraid, Chrome dev tools, Firebug, IE Dev Toolbar are the only options from a browser perspective. Any client side script will be part of the load and subject to delays before it starts execution.

There are tools to intercept and monitor the HTTP requests that can also give you this kind of information but again, it's not something that you can do without installation or user interaction.
