# Optimizing Symfony using APC

> Optimize Symfony PHP on a managed VPS with APC using this guide and code snippet.

This article describes how to optimize Symfony PHP framework code on a managed VPS using APC (Alternative PHP Cache).

## Optimizing Symfony with APC

You can optimize your Symfony PHP framework code on a managed VPS to run faster. To do this, use the APC (Alternative PHP Cache)**ApcClassLoader** class in your code as follows:

```
$loader = new ApcClassLoader('namespace_prefix', $loader);
$loader->register(true);
```

<Note>
  The APC namespace prefix can be any value you want.
