Проблема с nginx+apache

[Skyscraper]

Привет! помогите с такой проблемой:
имею ubuntu 10 + nginx+apahe [mod_php+xcache] 
крутятся joomla сайты и магаз joomla+virtuemart
не могу найти из-за чего тормозит
загрузка картинок, шаблон и текст
загружаются быстро, а вот с картинками
беда, идут в один поток по очереди...
мои конфиги:
