WP CLI Profile package allow use to identify the performance of our WordPress website.
Installation Installation
wp package install wp-cli/profile-commandSyntax Syntax
wp profile stage [<stage>] [--all] [--spotlight] [--url=<url>] [--fields=<fields>] [--format=<format>] [--order=<order>] [--orderby=<orderby>]
Where,
- 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 into the primary WP_Query.
- template: is where WordPress determines which theme template to render based on the main query, and renders it.
Usage Usage
Simple usage:
$ wp profile stage --url=https://maheshwaghmare.com/
+------------+---------+-------------+------------+
| stage | time | cache_ratio | hook_count |
+------------+---------+-------------+------------+
| bootstrap | 1.0081s | 97.73% | 23076 |
| template | 0.6028s | 96.27% | 6516 |

+------------+---------+-------------+------------+Here, We can see which stage takes much time when requesting the https://maheshwaghmare.com/ (home page) of our WordPress website.
Profile by Stages Profile by Stages
As we see by default we get the profile of all stages. But, We can debug the profile by providing the specific stage.
E.g.
wp profile stage <stage-name>We can pass additional parameters as: time, query_time, query_count, cache_ratio, cache_hits, cache_misses, hook_time, hook_count, request_time, request_count

$ wp profile stage bootstrap --fields=hook,time,cache_ratio --spotlight --orderby=time --order=DESC

We can debug the performance by hooks.
E.g.
wp profile hook <hook-name>We can pass additional parameters as: callback_count, time, query_time, query_count, cache_ratio, cache_hits, cache_misses, request_time, request_count
All Hooks All Hooks
We can debug all hook which is executed while visiting the specific page.

Profile by Function Profile by Function
We can also profile the functions.
Normal Function Normal Function
Suppose we have below function:
function my_test_loop() {
for ($i=0; $i < 5000; $i++) {
// Loop for 5000 time.
}
}Profile function my_test_loop() as below:
? wp profile eval "my_test_loop();"

| time | query_time | query_count | cache_ratio | cache_hits | cache_misses | request_time | request_count |
