## Overview
`wp profile` monitors key performance indicators of the WordPress execution process to help you quickly identify points of slowness.
2016-07-25 07:36:55 -07:00
Save hours diagnosing slow WordPress sites with `wp profile`. Because you can easily run it on any server that supports WP-CLI, `wp profile` compliments Xdebug and New Relic by pointing you in the right direction for further debugging. And, because it's a WP-CLI command, using `wp profile` means you don't have to install a plugin and deal with the painful dashboard of a slow WordPress site.
2016-07-25 07:36:55 -07:00
First, run `wp profile` to see metrics for each stage of the WordPress load process:
2016-07-25 10:17:10 -07:00
```
$ wp profile
+------------+---------+------------+-------------+-------------+------------+--------------+-----------+------------+--------------+---------------+
| stage | time | query_time | query_count | cache_ratio | cache_hits | cache_misses | hook_time | hook_count | request_time | request_count |
+------------+---------+------------+-------------+-------------+------------+--------------+-----------+------------+--------------+---------------+
| bootstrap | 2.0408s | 0.0365s | 15 | 93.21% | 412 | 30 | 0.9299s | 3097 | 0s | 0 |
| main_query | 0.0123s | 0.0004s | 3 | 94.29% | 33 | 2 | 0.0098s | 79 | 0s | 0 |
| template | 0.305s | 0.0175s | 179 | 91.02% | 2636 | 260 | 0.1125s | 7777 | 0s | 0 |
+------------+---------+------------+-------------+-------------+------------+--------------+-----------+------------+--------------+---------------+
| total | 2.3582s | 0.0544s | 197 | 92.84% | 3081 | 292 | 1.0522s | 10953 | 0s | 0 |
+------------+---------+------------+-------------+-------------+------------+--------------+-----------+------------+--------------+---------------+
2016-07-25 10:17:10 -07:00
```
Then, use `--stage=<stage>` to dive into higher fidelity of a particular stage:
```
$ wp profile --stage=bootstrap
+-------------------+---------+------------+-------------+-------------+------------+--------------+--------------+---------------+
| hook | time | query_time | query_count | cache_ratio | cache_hits | cache_misses | request_time | request_count |
+-------------------+---------+------------+-------------+-------------+------------+--------------+--------------+---------------+
| | 0.3558s | 0.0014s | 1 | 25% | 1 | 3 | 0s | 0 |
| muplugins_loaded | 0.0002s | 0s | 0 | 50% | 1 | 1 | 0s | 0 |
| | 0.8075s | 0.0007s | 6 | 73.68% | 56 | 20 | 0s | 0 |

| wp_loaded | 0.01s | 0s | 0 | | 0 | 0 | 0s | 0 |
+-------------------+---------+------------+-------------+-------------+------------+--------------+--------------+---------------+
| total | 2.166s | 0.0037s | 15 | 84.5% | 392 | 30 | 0s | 0 |
+-------------------+---------+------------+-------------+-------------+------------+--------------+--------------+---------------+
```
Lastly, when you've found a specific hook you'd like to assess, use `--hook=<hook>`:
```
$ wp profile --hook=plugins_loaded
+------------------------------------------------------------+---------+------------+-------------+-------------+------------+--------------+--------------+---------------+
| callback | time | query_time | query_count | cache_ratio | cache_hits | cache_misses | request_time | request_count |

```
