这是 php-fpm 配置文件

我使用 Shopify API 将其用作无头电子商务。API 的响应很快,但页面需要大约 12 秒才能加载,当我检查请求时,我发现几乎所有时间都花在等待服务器上,
即使我删除 API 调用,页面加载时间也相同
我想改善服务器响应时间,以便页面加载时间不至于达到 10-12 秒。我尝试减少和增加 pm.max_childern 和其他 pm 属性,但没有什么效果。我正在使用FROM php:7.2-fpm AS phalcon_build
。
是不是配置有问题导致页面加载缓慢?
答案1
您应该安装 xhprof,这样您就会看到时间花在了哪里。
使用 PECL (https://pecl.php.net/package/xhprof)
pecl install xhprof
并使用此项目中的xhprof_html
和xhprof_lib
来显示结果:https://github.com/longxinH/xhprof
答案2
是的,您的配置有问题,但主要问题出现在 PHP 执行中(或任何持久层,例如 PHP 下面的 DB)。
检查会话争用、不必要的 DNS 查找,并添加仪器来记录执行线程离开 PHP(即 http 调用、数据库调用、外部脚本)时的经过时间。
