> Xdebug's Profiler is a powerful tool that gives you the ability to analyze your PHP code and determine bottlenecks or generally see which parts of your code are slow and could use a speed boost.
https://xdebug.org/docs/profiler
When we run/start the web server, it would be useful to enable the trigger for the Xdebug's Profiler. That means we could easily trigger the creation of a Xdebug profile and analysing it [thanks to PhpStorm](https://www.jetbrains.com/help/phpstorm/analyzing-xdebug-profiling-data.html) which provides an **Execution Statistics** panel (examine the summary information about execution metrics of every called function) and a **Call Tree** panel (explore the execution paths of all called functions). You can see these two panels in action [here](https://youtu.be/_ua_O01IICg?t=1m22s) for a better understanding.
