我们有一个大型 Woocommerce 网站托管在 Google VM 服务器（E2 4vCPU + 32 GB RAM + 100 GB SSD 存储）上，最近我们使用 Flutter 和 WordPress -Woocommerce- API 创建了一个移动应用程序，但我们遇到了两个问题
- 获取数据非常慢，在高速互联网连接下加载产品可能需要超过 5-10 秒
- 如果用户使用该应用程序，网站将需要更多时间来加载或关闭，似乎服务器只能同时处理单个请求
环境详细信息
server NGINX + MySQL + PHP-FPM
PHP 7.4
OS: Centos 8
All tables Engin - InnoDB
我们做了以下事情
- 将 PHP.ini 内存限制增加到 128MB
- 将 PHP.ini 超时限制增加到 3000 秒，使用 cloudflare 链接网站。- 已安装缓存插件 W3 Total Cache
- 将 NGINX MAX 客户端增加到 250 个
我正在寻找关于如何允许服务器/MySQL 处理大量请求的建议。
