Very often I need to test some page speed and using bunch of websites, which produce very detailed information.

 

Here are some of them:

 

http://www.webpagetest.org/

This is the first one I’ve been using for a long time. Here are some of the features it supports:

• Select location from which the tests are going to be initiated

• Select the connection speed for the testings

• Select number of tests – This is very nice, because you can check the differences of loading the page WITH and WITHOUT caching in effect

• There are some other features also (which I’ve never used), and you can check them by going to the “Advanced” section

• You can get some public/private URL’s pointing to your test results – Again very useful if you want to send this to someone

 

http://gtmetrix.com/

Here again you get plenty of performance suggestions and also the following:

• Yslow grade
• Timeline waterfall view
• History chart – This is very handy and you can compare your performance results back in time with different version

http://tools.pingdom.com/fpt/

Pingdom has some nice features and as far as I know it’s also used for website availability monitoring.

The tests are issued very fast compared to webpagetest.org.

Again it gives you the standard information: waterfall view, performance history, Page analysis …etc.

Google pagespeed tool is included too. Here you get your mobile version performance suggestions as a bonus.
