lighttpd負載測試和優化

Question

我最近開始使用lighttpd而不是apache，並發現它更加實用和快速。

爲了讓我更進一步瞭解我的配置和其他工具，以便我的網站在線上的目的，在這裏他們是。

1. lighttpd的1.4.31
2. RAM - 2Gb的

max-procs = 2, PHP_FCGI_CHILDREN = 4, PHP_FCGI_MAX_REQUESTS = 10000

free ram -- 186 free and 652 cached

問題：

根據觀察，每當負載增加到4.00站點下降，我不知道爲什麼發生這樣。

我應該如何優化它，當我有足夠的內存來服務lighttpd。

Answer 1

這是我的lighttpd配置文件Typo3 + Fastcgi + Fam和低內存和積極調優。在我的web服務器使用Lighttpd而不是Apache進行服務器ram（512M）之前，我有了25M的免費ram，而Typo3的運行速度更快。我希望它有幫助嗎？
