Повышенная нагрузка на сервер баз данных

[lost1980]

пришло письмо от хостера, подскажите что к чему, первый раз такое

 

Повышенная нагрузка на сервер баз данных (предупреждение)

 

 

Уведомляем Вас, что работой базы данных MySQL u247757_6 создается повышенная нагрузка на сервер баз данных. Примеры запросов находятся в прикрепленном файле.

Оптимизируйте, пожалуйста, Ваши скрипты, SQL-запросы и дайте нам знать о результатах. Например, Вы можете использовать метод EXPLAIN для выяснения "тяжелых" запросов и создание индексов (CREATE INDEX), тем самым снизив нагрузку на базу данных

может дело во включенном показе количества товара в категориях? он в админке выключен но все равно показывается на сайте, как откл не знаю

Используйте любой модуль кеширования.

Смотрите модуль категорий, если он не стандартный то скорее всего не отключаемый показ.
