на некоторых страницах отрабатывает за 0,003 сек, а на некоторых за 2 сек, а то и за 5 сек. И как результат где-то время загрузки страницы 0,5 сек, а где-то 6 сек. Вопрос простой, можно ли оптимизировать и если да, то как mysql (не на уровне запросов, а на уровне сервиса mysql), что бы сделать запросы быстрее? Да и собственно почему такая разница? Заранее спасибо за ответ.

Re: Запрос долго отрабатывает

Разница из-за того, что в одном случае результат берется из кэша, а в другом выполняется? Планы выполнения отличаются у медленного и быстрого случая?
