PageSpeed Insights is a webpage that allow to check the performance of a web page (specially about load time and bandwidth) both for desktop and mobile, but also give suggestions to improve it solving some typical errors, and also there are extensions for Firefox and Chrome to run it locally :-) At this moment it give a 73% value for desktop and 63% for mobile, I'll try later to make Google scream a little bit more (pun intended ;-) ).
