我有一个每天有 10000 多个独立访问者的网站。服务器正在使用带有 PHP FastCGI 的 lighttpd。当同时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

请一些专家看看我的配置并建议我该怎么做？

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" 

                 )))

来自 Lighttpd 的 fastCGI 统计数据如下：

刚发现，是php脚本中调用glob函数的函数，当文件很多时，速度变慢会出问题
