Today, technology is at its peak. It has changed our lifestyle, beliefs, behavior and everything. We visit hundreds of websites and blogs in a day. Sometimes we think about a site’s performance and want to compare a site with another. We try to compare them by speed. Today I am going to tell you some online site performance tool by which you can compare two sites and their performance or you can also check a single site’s performance.1. Google’s PageSpeed Insights
This is a very useful online tool which will give you a pretty good idea about a site’s performance. Just enter the website’s URL and it will list out the entire report as per their priority. If you are a website’s owner then this will help you a lot. It will give you all possible suggestions that you can do to increase your site’s performance. I personally liked this service a lot because it has been made by big G.
2. Yslow
This is a very useful plugin for Firefox made by Yahoo to check whether a site is slow as per Yahoo’s rule and the reason for being slow. This will give you a detail report about javascript, different components, images, CSS, DOM elements associated with the webpage. Some sample suggestions given by Yslow are:
- Avoid empty src or href
- Put CSS at top
- Put JavaScript at bottom
- Avoid URL redirects
3. GTmetrix
This is a very old website which will generate a detail report about a webpage based upon different factors like Minify JavaScript, Avoid bad requests, Optimize images, Remove unused CSS and many more. This is a bit user friendly website because for each factor it will show you a grade and also it will show you the detail reason for getting low grade in a particular factor.
4. WhichLoadsFaster
This is a very interesting place to compare two websites side by side. Just go the website, enter two URLs and press enter. It will analyze for a second and show you which one is faster and how much time faster. Following image shows a sample output of the website.
