Оптимальные настройки VPS

Доброй ночи!

Есть VPS с Intel Xeon CPU E5620 2.40GHz и 2ГБ оперативки, на нем висит сайт-каталог на Wordpress с посещаемостью 500-600 уников в сутки. Минус этого сайта в том, что он использует огромное количество запросов к БД ( на внутряках от 100 до 300 на главной (это с базовой оптимизацией запросов) ). Кажется, что настройки у сервера неоптимальные. Какие оптимальные настройки для такого VPS? Конфиг mysql прилагаю.
