Сокращение часов работы экземпляра CloudSQL (wordpress)

У меня есть установка WordPress на GAE. Это веб-сайт, который будет очень редко обновляться и будет иметь несколько посетителей каждый день (максимум 100 человек). Я хотел бы кэшировать этот веб-сайт, чтобы минимизировать затраты на cloudSQL.

Какие шаги следует предпринять, чтобы свести к минимуму запуск моих экземпляров CloudSQL?

Я установил плагин MEMCACHED и мой плагин BATCACHED.

мой wp-config имеет следующее:

$batcache = [
      'seconds'=>0,
      'max_age'=>300*60, // 300 minutes
      'debug'=>false
    ];

Мое приложение.yaml:

application: MY ID
version: 104
runtime: php
api_version: 1
default_expiration: "1d"

Я хотел бы знать все способы уменьшить WordPress при запуске моего экземпляра CloudSQL. Кроме того, я хотел бы знать, как проверить, правильно ли работает кеширование или нет.

в настоящее время, даже когда я посещаю страницу без входа в WordPress, он показывает запущенный экземпляр CloudSQL (одно активное соединение), чего, я считаю, не должно быть, если кэширование работает правильно
