netwind:
Dram, я так сложно пишу или что? почему бы не проделать описанные мной манипуляции ?

Vin_cent:
Размер базы разный

zzzit:
Да можно многими способами много всего посмотреть.
Но самое интересное, что этот запрос даже в теории не может создавать такой картинки с нагрузкой процессами апача, как показал ТС.

admak:
Да, так и есть, функции даты/времени не кешируются. Тоже наступал на похожие грабли.
Или грабли, а потом чтение доки mysql по кешированию.
