How can I speed up view partials?

Those who use partials heavily and who profile their applications will often immediately notice that the partial() view helper incurs a lot of overhead, due to the need to clone the view object. Is it possible to speed this up?

Use partial() only when really necessary

The partial() view helper accepts three arguments:

  • $name: the name of the view script to render

  • $module: the name of the module in which the view script resides; or, if no third argument is provided and this is an array or object, it will be the $model argument.

  • $model: an array or object to pass to the partial representing the clean data to assign to the view.

The power and use of partial() come from the second and third arguments. The $module argument allows partial() to temporarily add a script path for the given module so that the partial view script will resolve to that module; the $model argument allows you to explicitly pass variables for use with the partial view. If you're not passing either argument, use render() instead!

Basically, unless you are actually passing variables to the partial and need the clean variable scope, or rendering a view script from another MVC module, there is no reason to incur the overhead of partial(); instead, use Zend_View's built-in render() method to render the view script.
