Sitespeed.io - how speedy is your site? 
Sitespeed.io is a tool that analyzes web sites and give you information of why they are slow and how you can optimize the web performance. Yslow rules in combination with other best practices rules are used.
What do sitespeed.io do?
You give sitespeed a start point, the first page on your site, where you want it to start crawl. By default, one level will be crawled, meaning all links (on the same domain as the main page), will be fetched & analyzed.
The flow looks something like this:
