wp profile stage

Profile each stage of the WordPress load process (bootstrap, main_query, template).

When WordPress handles a request from a browser, it’s essentially executing as one long PHP script. wp profile stage breaks the script into three stages:

  • bootstrap is where WordPress is setting itself up, loading plugins and the main theme, and firing the init hook.
  • main_query is how WordPress transforms the request (e.g. /2016/10/21/moms-birthday/) into the primary WP_Query.
  • template is where WordPress determines which theme template to render based on the main query, and renders it.
# `wp profile stage` gives an overview of each stage.
$ wp profile stage --fields=stage,time,cache_ratio

# Then, dive into hooks for each stage with `wp profile stage <stage>`
