Measuring Site Speed localy

This is a cool utility that uses YSlow! and PhantomJS to measure your site’s speed across many pages. Should be good for identifying slow individual pages as well as practices that impact multiple pages.

This is how it works: You feed it with a start URL and how deep you want it to crawl. The pages are fetched and all links within the same domain from that page are analyzed, and a couple of HTML pages are created with the result. Sounds simple?
