Про кэш мускуля ответьте :)

Я так понял кеш включен по умолчанию, query_cache_type=1 не обязательна

Не понятно главное - как два в принципе одинаковых сервера - могут так по разному переносить нагрузку.

Значит дело в настройках

Самый посещаемый сайт, после переноса которого и выросла нагрузка - имеет базу размером 734.814 МБ

поиск ГРЕПОМ по старому IP уже делал - в скриптах нет ничего, направленного на старый

Вот немного мунина. Обычно в будни запросов у меня до 500 в сек. Но щас выходные - траф на минимуме

Смарт дисков Админ смотрел 1 делом, сказал все ок. Да они были чуть медленее чем старых, но не критично

А если вывести atop? Что там у нас?
