Question

我每天都有一个拥有超过10000名访客的网站。服务器正在使用带有PHP FastCGI的lighttpd。当并发在线访问者达到高数量（即超过180）时。服务器遇到更高的负载和非常慢的响应。我启用了Xcache，并使用了Php5.3。服务器负载：23.74,18.78,10.97

有些专家可以看看我的配置，并建议我做什么？

fastcgi.server = ( ".php" => ((
                     "bin-path" => "/usr/bin/php5-cgi",
                     "socket" => "/tmp/php.socket",
          "min-procs" => 1,
        "max-procs" => 5,
        #  "max-load-per-proc" => 8,
             "idle-timeout" => 30,
            "bin-environment" => (
              "PHP_FCGI_CHILDREN" => "10",
              "PHP_FCGI_MAX_REQUESTS" => "500" 
         ),
    "broken-scriptfilename" => "enable" 

                 )))

Answer 1

刚刚发现，这是PHP脚本中的一个函数，调用 glob 函数，当存在大量文件时，速度变得很慢会导致麻烦

在高流量下配置Lighttpd FastCGI
