+# Profiling code with Xdebug PHP Profiler
+
+Create a modified xdebug.ini to your project's root:
+```ini
+zend_extension=/usr/lib/php83/modules/xdebug.so
+xdebug.mode=profile
+xdebug.output_dir=/app/xdebug
+xdebug.profiler_enable=1
+xdebug.profiler_output_name=cachegrind.out.%p
+xdebug.use_compression=false
+```
+
+Create a `Dockerfile.profile` file in your project's root:
+```bash
+ARG DRUPAL_IMAGE
+FROM ${DRUPAL_IMAGE}
+
+COPY xdebug.ini /etc/php83/conf.d/50_xdebug.ini
+
+RUN mkdir -p /app/xdebug
+```
+
+Modify your `compose.yaml` file:
+
+```diff

+Load the page you want to profile and check that the log files start to appear in project's `xdebug` folder.

+Use [qcachegrind](https://formulae.brew.sh/formula/qcachegrind) (for Mac) or [kcachegrind](https://kcachegrind.github.io/) (for Linux) to open the log files in a GUI.
