drupalcon 2014: next generation php performance

Tired of reading semi-trustworthy benchmarks about the new hotness? Want the straight dope on what to think about to make your site screaming fast? This is the session for you. From the original creator of Pressflow and the packager of the Mercury performance AMI (and two co-founders of Pantheon) — a look at the next generation of PHP performance, and what it means for Drupal. PHP is undergoing a renaissance: the core development community is moving ahead, and with large entities like Facebook making significant contributions, the often-mocked language that powers most of the web is looking better than ever. Recently there have been a number of major innovations, but there seem to be more questions than answers; What's with PHP 5.5 and its new integrated opcode cache? How fast is Hip Hop Virtual Machine (HHVM) really? How can we take advantage of parallelized processing? SSDs? How much do they help? We'll break it down: solid numbers, real world use-cases, and what you can do to build the fastest application possible.
