Apache2 页面服务速度极慢 - 请查看服务器状态

过去一周，我的 VPS 上的网站加载速度非常慢，有时甚至会超时。您能否查看我的 Apache2“服务器状态”输出，如果发现任何有趣的东西，请告诉我？我看到很多“OPTIONS * HTTP/1.0”请求，其中客户端是本地主机 (127.0.0.1)。我真的不知道发生了什么。

任何帮助将不胜感激。

缺口。

您的设置中是否运行了 cPanel？cPanel 使用“OPTIONS * HTTP/1.0”来检查服务器的状态，但它本身不会对服务器造成任何额外负载，因此我猜想还有其他问题，而且如果没有您提供的其他信息，很难提出其他建议。

检查状态页面以及浏览时http://www.sweetboxing.com和http://www.sweetmma.com它回复我很快。/server-status 页面也没有显示任何当前高负载，所以现在对你来说可能也很平静？

通常，您必须在页面加载缓慢时观察服务器，以便更好地了解问题所在，例如 Apache 是否配置为允许太少的连接，是否在高使用率下内存不足。也许您受到了攻击，或者只是有人从您的网站链接了一些热门内容？事后阅读日志以及在发生事件时主动监控性能通常会为您提供更多详细信息。

我确实认为，这个块的低值是导致您有时出现排队和性能低下的原因。尝试以下方法：

<IfModule mpm_prefork_module>
StartServers 10
MinSpareServers 5
MaxSpareServers 5
MaxClients 100
ServerLimit 100
MaxRequestsPerChild 100
</IfModule>
