On the PHP North West site today they've released another in their series of video recordings from this year's event. In this session Lorenzo Alberton talks about profiling your application to squeeze out as much performance as possible.
Making an application scale and go faster is often seen as a wizardly task. We read the micro-optimisation tricks posted in tech blogs and apply them with unconditional trust and great hope, and then wonder why performances haven't improved that much (Wait, I even replaced print with echo!!!).In this talk well see how we can take easy, practical steps we can apply over and over that really make a difference, by analysing what our application does under the hood, measuring how and where the different resources are used, eliminating the real bottlenecks and restructuring critical components to handle growing loads.
