Google has released a new tool called Page Speed Online that allows users to instantly get a report detailing the performance of their website. Simply enter a URL and you will get information on how your pages ranks on a scale of 1-100. Also you can get a mobile report as well. This is nice because when writing mobile apps many developers forget that compression and minifcation are very important. I have used tools in the past like YSlow to get a very detailed report of my site, but this tool by Google is much more lightweight and easier to interpret.
Page Speed Online does a decent job of quickly analyzing your site, but it does not tell you any of the load times of all the elements of your page. YSlow does do this and it is helpful to see what is actually taking so long to load on your page. Both tools tell you the obvious things, like set expires headers on images and minify JS/CSS.
Overall, I think it is a fast way to get an analysis of your site. But the suggestions are things you probably already know anyways and just decided not to do. Also I got two different scores that differed by 10 points within the same day which was strange.
