Magento Site Performance Optimization

Chapter 4
• If you become addicted to performances, HHVM is now supporting
Fast-CGI through Nginx and Apache. You can find out more about that at:

Summary
In this final chapter, we learned how to take advantage of different caching
mechanisms in order to store—instead of recomputing—the requests of your
customers, in terms of HTTP requests, PHP byte code, random objects, and
dynamic blocks using Varnish, APC, memcached, and Lesti::Fpc, respectively.
We also successfully used the HHVM from Facebook to serve Magento. This last
improvement brings incredible performances.
Overall, this book allows Magento to be served in a fraction of the time required
before. Indeed, the default time was over 110 seconds for our stress test, while the
required time at the end of this chapter is less than 5 seconds. In conclusion, using all
the technics seen in this book will result in Magento being sped up 20 times faster, if
you are fearless enough to use HHVM, or 6 times otherwise.
