Использование WP-CLI для диагностики проблем производительности WordPress
Сейчас мы покажем вам, как установить профиль wp и эффективно использовать его для определения узких мест производительности на вашем сайте. мы рекомендуем тестировать профиль wp на промежуточных серверах, так как нет других переменных, влияющих на время загрузки.

Установка пакета wp-profile

Выключите эту команду, чтобы установить wp-профиль.

wp package install wp-cli/profile-command

 

Вы должны увидеть, что процесс успешно установлен и теперь доступна команда профиля wp

Installing package wp-cli/profile-command (dev-master)
Updating /root/.wp-cli/packages/composer.json to require the package...
Using Composer to install the package...

Success: Package installed.

 

Если вы видите эту ошибку «Killed» при попытке установить wp-профиль, ее можно исправить с помощью файла подкачки и/или обновления php.ini для cli, memory_limit = 256M

Installing package wp-cli/profile-command (dev-master)
Updating /root/.wp-cli/packages/composer.json to require the package...

Killed

 

Данная команда ниже создает файл подкачки объемом 1 ГБ. Для создания файла подкачки вам потребуется root-доступ.

swapoff -a 
dd if=/dev/zero of=/swapfile bs=1M count=1024

 

Увидим этот результат

1024+0 records in 
1024+0 records out 
1073741824 bytes (1.1 GB, 1.0 GiB) copied, 2.16717 s, 495 MB/s

 

Измените разрешения файла подкачки и превращение его в своп

chmod 600 /swapfile 
mkswap /swapfile 
swapon /swapfile

 

Затем заново запустите команду установки профиля wp

wp package install wp-cli/profile-command

 

Теперь вы должны увидеть успешный вывод

Обновление профиля wp

Вы можете обновить до последней версии пакет с помощью этой команды

wp package update --allow-root

Использование команды wp profile

Войдите в каталог WP (или используйте –path )

Этапы команды wp profile

Эта команда показывает этапы загрузки WordPress.

wp profile stage --allow-root

 

Вы получите эту таблицу с подробной информацией. В основном ваш фокус должен быть на столбце time.

В общем, вы хотите, чтобы ваш cache_ratio быть высоким, более 70%

Как правило, вы хотите, чтобы cache_hits был больше, чем cache_misses

Ваш query_time должен быть низким

+------------+---------+------------+-------------+-------------+------------+--------------+-----------+------------+--------------+---------------+

Может быть развернута на каждом этапе, здесь мы переходим на стадию bootstrap

wp profile stage bootstrap --allow-root

 

Затем вы увидите хуки, используемые на этом этапе

Обычно мы предпочитаю использовать флаг -all для команды stage

wp profile stage --all --allow-root

 

Эта команда покажет все хуки, используемые на каждым этапе

Для более подобного этапа для профиля wp, можете использовать флаг –all для перехватов.

wp profile hook --all --spotlight

 

Вы можете даже имитировать загрузку для определенного URL-адреса на сайте с помощью флага –url .

wp profile hook --all --spotlight --url=https://andreyex.ru --allow-root

 

Похоже, загружается только моя тема GeneratePress, Yoast и WP Theme Optimizer.
