Site speed can be an important search engine optimization benchmark, and it can greatly affect the amount of time visitors spend on your site. The faster your pages load, the better.
I've used some of these tools on my own blogs, and I've had great results. My page loading times went from up to six or seven seconds down to one to two seconds most of the time. That's a huge improvement.
The official description of each tool appears under the link.
Page Speed Insights measures the performance of a page for mobile devices and desktop devices. It fetches the url twice, once with a mobile user-agent, and once with a desktop-user agent.
The PageSpeed Score ranges from 0 to 100 points. A higher score is better and a score of 85 or above indicates that the page is performing well. Please note that PageSpeed Insights is being continually improved and so the score will change as we add new rules or improve our analysis.
