Question

我正在使用WordPress Nginx的fastcgi-cache并且在php-fpm中具有高CPU使用率我跟踪了这个过程所有人都给了我同样的东西

gettimeofday({1399054255, 543565}, NULL) = 0
gettimeofday({1399054255, 543621}, NULL) = 0
gettimeofday({1399054255, 543678}, NULL) = 0
gettimeofday({1399054255, 543739}, NULL) = 0

- 并统计所有过程做同样的事情我在过去的5天里搜索了很多，我测试了所有我能做的事情我已经更改主题禁用插件我做了新的wordpress安装，但没有我已经将php-fpm配置文件更改为可能的所有内容

这是我现在的配置

pm = dynamic
pm.max_children = 10
pm.start_servers = 4
pm.min_spare_servers = 2
pm.max_spare_servers = 6
pm.process_idle_timeout = 10s;
pm.max_requests = 200

我没有访客即使我是cpu唯一的访问者，直到此过程结束才达到100％

gettimeofday( NULL) = 0

整天

gettimeofday({1399054255, 547438}, NULL) = 0
gettimeofday({1399054255, 547564}, NULL) = 0
gettimeofday({1399054255, 547665}, NULL) = 0
gettimeofday({1399054255, 548304}, NULL) = 0
gettimeofday({1399054255, 548415}, NULL) = 0
gettimeofday({1399054255, 548517}, NULL) = 0

请帮助这令人沮丧
