Доброго времени суток.
Помоги пожалуйста правильно настроить и оптимизировать базу.
Нагрузка на сервер постоянно растет. Скоро в очередно раз прийдется нарасчивать мощность.
Может я просто что то не так делаю?

SHOW GLOBAL STATUS в этом отношении информативнее.
Включите журнал медленных запросов и посмотрите за тем, что там
попадается. Возможно, проще просто несколько запросов пооптимизировать.

А как включить журнал медленных запросов?
Мне уже системный администратор с помощью какой то программы показывал где не хватало индексов. Исправили, но количество пользователей постоянно растет соответственно и нагрузка тоже.
Если необходимо я могу кинуть результат SHOW GLOBAL STATUS
Заранее благодарю за ответ.
