# Xhprof

# Profiling the Pixwel API

The current Docker image ships the **[Excimer](https://www.mediawiki.org/wiki/Excimer)** sampling profiler (installed in `docker/app/Dockerfile`), not XHProf.

> The instructions below are the legacy **XHProf** flow from the Vagrant/demo-node era, kept for historical reference. They no longer apply to the Docker setup.

[XHPROF](https://github.com/phacility/xhprof) was installed automatically on demo and vagrant nodes. You'd SSH into the machine, edit `/opt/pixwel/pixwel-api/webroot/index.php` and uncomment (or add) the line:

```php theme={null}
$xhprof = extension_loaded('xhprof');
```

Then check port 82 of your demo branch (e.g. [http://optimise-startup.demo.pixwel.com:82/](http://optimise-startup.demo.pixwel.com:82/)).
