我们 site 上的所有 8 个 vCPU 使用率均为 100%。
我们的用户经常看到以下消息，
由于负载极高，目前暂时以未登录用户看到的方式向所有人展示。
我们的 Droplet 规格如下：
CPU-Optimized / 16 GB / 8 vCPUs , Intel Dedicated Digital Ocean Droplet

截至撰写本文时，Google Analytics 上的实时在线用户数约为 70 到 150。
以下是 CPU 和内存使用情况的 htop 截图，
Digital Ocean 过去 14 天的使用情况图表：
App.yaml 内容如下，
db_shared_buffers: “4096MB”
db_work_mem: “400MB”
UNICORN_WORKERS: 16
#- “templates/web.ratelimited.template.yml” #removed this to avoid 429 too many requests errors Remove the ip limits
如图所示，我们注释掉了 ratelimited 模板，因为它导致我们的普通用户在网站实际流量很低的情况下仍然遇到 429 nginx 请求过多错误。

问题：
-
这是针对论坛的 DDoS 或暴力破解攻击，还是某些机器人的流量？
或者是真实的流量，我们需要升级 droplet（虚拟主机）规格？如果是这样，我们应该升级什么，升级多少？ -
我们现在该怎么做？目前，我们的 网站 加载非常缓慢，从一个主题导航到另一个主题时，加载过渡时间超过 5 秒。
-
如何找出哪些流量或资源消耗了如此多的流量？是真实的人类流量，还是试图瘫痪我们网站的机器人？
-
如果我们决定升级 droplet 规格，应该在 app.yaml 中做哪些更改？
-
在用户个人资料管理页面，我们可以看到每个用户的唯一 IP，这意味着 Cloudflare (CF) 获取了真实 IP。但是，为什么当我们取消注释 app.yml 中的 ratelimited 模板时，会出现 429 请求过多错误？
-
我们应该如何配置 CF 的 DDoS 设置？
-
有没有办法配置我们的服务器/Discourse 以多线程或并行方式工作，以使用我们当前相同的 droplet 规格来支持高流量？如果有，如何配置 Discourse 中的多线程/并行扩展，以有效且最优的方式利用多核/CPU 的 droplet？
我们使用了 Cloudflare，当开启 CF 的“正在遭受攻击”模式时，CPU 使用率会下降，但我们不能每次用户使用我们的网站时都让他们解决验证码，这会烦扰我们的新用户。目前 CF 的机器人对抗模式已开启，CF 的安全级别设置为高。
我们尝试过重建，但在重建完成后，情况恢复正常，但几分钟后 CPU 使用率又回到 100%。
请有人帮帮忙。
