PageSpeed Service is an online service to automatically speed up loading of your web pages. PageSpeed Service fetches content from your servers, rewrites your pages by applying web performance best practices and serves them to end users via Google’s servers across the globe.
“Users prefer faster sites and we have seen that faster pages lead to higher user engagement, conversions, and retention,” said mod_pagespeed technical lead Joshua Marantz and Ilya Grigorik, developer advocate for Google’s Make the Web Fast project.
It was a two year project and Google has taken beta label off the software today. It’s already in use at more than 120,000 sites and offered as an option for site hosting firms at DreamHost and Go Daddy.
The service improves on previous offerings from Google. It began as a diagnostic tool and then with every step, Google has increased the ease and automation of the service. “Instead of telling people what the problems are, can we just fix it for them automatically?”, says Richard Rabbat, a product manager for the initiative.

As per Technology Review : PageSpeed will be a handy resource for smaller sites with little to no complexity, whose owners don’t have developer time to pour into hand-tuning their sites, or the money to put into investing in an advanced performance automation solution.
