Sander van de Graaf has put together a new post for his blog today that looks at a few ways you can optimize your Zend Framework application.

So, to squeeze the most out of their current setup, Sander worked through the process to see how their machine perform and a dew things that they did to give them a bit more of a boost. There's some general tips (like Apache settings) and some more PHP and Zend Framework specific suggestions.
