Aaron Brazell • @technosailor • • Every Time WordPress loads a page, events are fired. • Plugins typically hook events into init, admin_init, plugins_loaded, or save_post to fire events • Every event takes time to complete • Many dozens of events, all waiting to finish running, add overhead to WordPress.

T E C H C R U N C H A S Y N C L I B R A RY • TechCrunch had extremely long process times, particularly with their CrunchBase API. • API calls were required to repopulate cached results. • Eric Mann (@ericmann) and John Bloch (@johnpbloch) built a library to offload tasks to asynchronous equivalents • Runs on `shutdown` hook Photo Credit: Charlyn Wee, via Flickr Creative Commons

It can also be installed as a standalone plugin. • Create a subclass that extends WP_Async_Task • Include a prepare_data() and run_action() method (Details in the documentation) • Include a protected $action variable that is set to the hook name you wish to run asynchronously. • Hook events on wp_async_{$action} (e.g. wp_async_transition_post_status)
