Laps is a plugin that **shows performance information** about WordPress page load.

It provides a visual summary in toolbar that is quick and easy to inspect.

## Page profiling

Laps automatically tracks many events, such as:
- PHP, core, plugins, and themes load, main posts loop, sidebars
- database queries (with [`SAVEQUERIES` constant](http://codex.wordpress.org/Editing_wp-config.php#Save_queries_for_analysis) enabled)
- network requests to other sites 

## API profiling

For Ajax and REST API — Laps outputs performance information by Server Timing API, for use with clients such as Chrome Dev Tools.

Note that REST API requests need nonce to be fully authenticated with cookies and show the information. Alternately `laps_can_see` check can be filtered.
