Every developer should be confident that their code is efficient and safe to run in production. But it can be hard to get started. What tools to use? What do the graphs mean? What to look at first? In this talk, we will analyse and optimise the performance of a simple PHP application. By demonstrating how to use some of the excellent open source projects such as xdebug, xhprof or meminfo I hope to give you a good idea of where to start with analysing and optimising your PHP code.

Very good pointers and tools explaination.
4 stars due to basics examples: I always prefer to have real use cases that not involves model knowledge then too obvious ones.

Great overview, good tool list. Could use some more meat with php-meminfo, felt a bit short in the end.

When developing mobile apps, I've had to optimise them once built. With web development I never even thought of it. These techniques just showed me I can do it and I need to do it. I liked the keynote.
