React, Flux, GraphQL, Hack, HHVM...? All of this and more!
Drupal 8, a CMS using Symfony Components and other significant improvements under the hood is out in November 2015. This is a great effort, but the sites built with Drupal 7 will continue to run for a number of years. Due to the limited number of modules for Drupal 8, even new Drupal 7 projects will be started.
The major iteration of the PHP language, PHP 7.0.0, is also scheduled for release the same November. Drupal 8 will get PHP 7 compatibility soon, but for Drupal 7 the schedule is open. Read more about the status of Drupal and PHP 7 compatibility.
In short, the best option to increase Drupal 7 performance today is to switch to running the HHVM virtual machine designed to run PHP at high performance. Support for PHP 7 will come at a later date.
People love to pit two competing products together. Be it sports cars, cameras or software. Everyone likes to cheer for their personal preference. This is now happening with PHP 7, HHVM and others inspiring people to create pointless benchmarks.
NGINX is a very popular web server which is becoming even popular than the previous king Apache. NGINX has very high performance and this makes it a perfect companion for the HHVM PHP Runtime using Fast CGI interface. NGINX and O'Reilly have teamed up to give you access to a new eBook about NGINX, A Practical Guide to High Performance, for a limited time.
