In this chapter, we have covered a few projects that went along with Google's new initiative of a Faster Web. We have seen what the HTTP/2 protocol is all about and how the SPDY project made it possible, how PHP-FPM and Zend OPCache can help you boost the performance of your PHP scripts, how to use ESI technology by setting up a Varnish Cache server, how to use client-side caching, and how other Faster Web tools can help you out when trying to optimize your web server's performance.
In the next chapter, we will see how, when everything seems to have been fully optimized, we can still go beyond performance.
