Как уменьшить TTFB на Nginx + Fastcgi

[sytrus]

Здравствуйте, пользуюсь vestacp недавно, поэтому возникли трудности с настройкой. Связка Nginx+phpfpm на кеше fastcgi дает громадный ttfb (0.9с). В настройках nginx включен кеш, но к сожалению это не поменяло ситуацию. Сайт на cms wordpress.

Если надо линк на сайт, скину в лс. Конфиги nginx (domain заменил в целях конспирации :-) ):

Думаю, что нужно читать и оптимизировать:

* http://serverfault.com/questions/350062 ... first-byte

Очень похоже на религиозный вопрос с этим первым байтом, как по мне :)
