Why the results vary so much? - xLinda - 05-05-2014 11:41 PM


I'm trying to optimize our company site and I'm testing via webpagetest.org. Hower, the results vary widley, while I use the same settings. Can anyone tell me what this is? I can't figure it out.

Here are the results:

I believe that you are using Wordpress...

The main reason would be 9 JS files and tones of image files in your website.

If you are using wordpress try to install and play with W3-Total-Cache which combines and minifies JS/CSS files plus the HTML output.

The other thing would be optimizing the image files used on your website and removing and replacing them with google font icons if possible.

Serving file through CDN would be another great solution to improve your website's page load time.

Those results are comparable. There's not really all that drastic of a difference between them.

You are showing to be loading nearly 2.5 megabytes on chrome, but well over 4 megabytes on IE. You can greatly reduce this pageload by optimizing the images. When you run the test using a IE browser you find out your images are NOT optimized and you get the real picture of what is going on.

Always optimize to IE, since it is the most difficult, worse case browser to comply with. If you are IE optimized, the rest of the browsers are good to go.

Testing with Chrome - which is essentially just Apple's Safari browser dressed up nicer - doesn't give you the true picture.

This page shows all of your images and also which ones need work. WPT actually does the work for you, click where you see "Analyze JPEG" and the site will generate the progressive, optimized JPEG for you, on each one, for free.

A fat site is going to be a slow site, every time.

You should also go in and fix that keep-alive issue. That should mostly solve the issue of the bandwidth not being fully utilized.
