I will share the practical techniques that I use to identify and resolve performance bottlenecks in PHP applications. You will learn how to visualise your software's execution, pinpoint slow units of code and inefficient call patterns, measure execution costs under controlled conditions and spot regressions across versions or changes.

Using real-world examples from my experience, I will demonstrate how I progress from identifying a perceived slowdown to gaining actionable insights. Whether you are developing business-critical APIs or large-scale web platforms, this presentation will hone your ability to diagnose and resolve performance issues with confidence.
