Symfony keeps evolving adding new features, fixing bugs and reorganizing its structure to support more and more projects. But Symfony also evolves in term of performances. This talks will detail how the PHP 7 engine works, how memory and CPU are used in the heart of PHP, how classes, objects, variables and arrays work. Then we'll see how Symfony got patched to take care of the latest optimizations brought to the PHP engine. We'll dive into OPCache, into the memory manager and the internals of PHP 7 to notice why Symfony's code has been patched in such ways that it now performs better.

Interesting topic. It is nice to know about the PHP internals. Only complaint is that most of the things were really behind the scene and less optimization I can do myself.

This was very interesting talk and is nice to see things under the hood of PHP. I learn some new tricks for optimizing code. I think all developers, php developers, should know at least basics how things are done below surface

Good topic and good speaker. The connection wasn't always apparent, but it was a great insight into the internal workings of PHP and the engine.

Nice talk and presentation (https://www.slideshare.net/jpauli/symfonycon-2017-php7-performances)

Great talk about PHP optimizations. It is always interesting to know how the PHP engine works.
