Padraic Brady has posted the appendix for his book "Zend Framework: Surviving the Deep End" that can be found here.

This week's chapters explores some of the performance issues and tactics worth being aware of when developing Zend Framework, and indeed other, applications. It's a rather long piece of work but I hope it proves enlightening. Comments are, as usual, welcome and you can attach them to any paragraph in need of attention.

Next up will be a chapter focusing on the Model portion of the MVC structure, so keep an eye to his blog for more chapters as they're released.
