Question

我的服务器有问题：它是旧的I3-2130 （很好，真的）， 8 gigs RAM ，另外还有500个SWAP。

>

首先，我有大量的域名，现在大约是5k，我计划将其增加到5万

我不使用mysql -对我来说太慢了。我有一个没有任何数据库的自残php-mini-cms-只是php和文件。真的很快。
PHP 7.3，已启用Opcache -非常快。在0.2秒内运行时，我的脚本占用了大约15％的处理器核心。就是这样。
我的 nginx版本是1.14.2 （它与Vestacp一起安装，并且有4个主要进程- Nginx，php-fpm，fail2ban和iptables -我已经封锁了某些国家/地区）。我已禁用任何域的 ANY 日志记录。

这是我的根Nginx配置：

看：我已禁用multi_accept，而worker_processes仅2个！

现在使用的内存是Nginx内存：3212 mb和php-fpm-从500兆字节到3000 RAM。是否有可能减少Nginx的内存RAM？

问题是-机器人！可能是30-40洛杉矶，但我的问题是- NGINX下降。我找不到原因。我不想每天检查-跌落或不跌倒-

也许这里是人们，他们在众多领域中都知道吗？为什么会掉下去？跌倒时-它不会将任何内容写入主错误日志。

NGINX属于大量领域
