我真的不明白为什么这么慢。
网站加载非常缓慢。 和vboxheadless命中超过100％CPU每个请求。
我使用2048内存和1个CPU。

这是我的/var/log/error.log：

php53看起来是一样的，但加载5.3。
这是我的网站conf：

我有两个主机看起来非常像上面，但与不同的serveralias和不同的PHP。
我的fastcgi.conf是空的。
mpm_worker.conf：
# worker MPM # StartServers: initial number of server processes to start # MinSpareThreads: minimum number of worker threads which are kept spare # MaxSpareThreads: maximum number of worker threads which are kept spare # ThreadLimit: ThreadsPerChild can be changed to this maximum value during a # graceful restart.

我能做些什么来解决这个问题？
