Всем привет есть VPS 8 Озу + процессор 2 ядра. на сервер нагрузки особо не много около 300+ посетителей в сутки.
но заметно бывает тормозит MYSQL долго отдает ответы. может кто даст рекомендации какие параметры стоит покрутить для поднятия быстродействия MYSQL.
может накрутил я лишнего.
за ранее спасибо.
