在页面加载时提供随机文件时服务器挂起

我正在优化一个网站，现在面临的问题与服务器有关。在页面加载期间，大约有 40-50 个请求发送到服务器（取决于页面），并且在每种情况下，服务器在某个文件上挂起大约 5-6 秒（主要是图像，因为 css 和 js 正在合并），或者两三秒。。看看 firebug 屏幕截图，以更好地了解我在说什么

（这里有 90 个请求，因为 js 和 css 尚未合并）。
网站是比奇洛化学家。知道是什么原因造成的吗？我可以更深入地研究一下，我只是需要一些提示来了解这种行为可能的原因。谢谢

看来您的网络服务器没有配置为处理那么多的请求。

  • 使能够活着

    # KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 200

  • 调整服务器参数以获得足够数量的进程处理并发请求

    # prefork MPM
# StartServers: number of server processes to start
# MinSpareServers: minimum number of server processes which are kept spare
# MaxSpareServers: maximum number of server processes which are kept spare
# MaxClients: maximum number of server processes allowed to start
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule mpm_prefork_module>
    StartServers          5
    MinSpareServers       5
    MaxSpareServers      50
    MaxClients          150
    MaxRequestsPerChild   0
</IfModule>

# worker MPM
# StartServers: initial number of server processes to start
# MaxClients: maximum number of simultaneous client connections
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule mpm_worker_module>
    StartServers          5
    MaxClients          150
    MinSpareThreads      25
    MaxSpareThreads      75
    ThreadsPerChild      25
    MaxRequestsPerChild   0    
</IfModule>
