Waiting ttfb first byte loading slowly searched the whole network and couldn't find the reason. Ask the kind-hearted person to take a look (wdcp panel)

as mentioned in the question, the first byte loads slowly. The speed of the test site is usually 1-10 seconds or more.
searched all over the network but couldn"t find the reason. Collapse causes

mine is wdcp panel
I am nginx (1.8.1) + apache dual system, the website uses php7.14, so nginx is main, I switch to nginx single system, pseudo-static can not turn the page. Looks like apache still works? There are also plug-ins that use zend.
my server is Aliyun"s 1-core 2G memory, 5m bandwidth, Aliyun CDN + OSS image CDN. But the first byte is still very slow! ~
(less than 1000 people a day if there is not much traffic on the site)

the following is my DZ system information

that's not a problem. It's just that your website is slow. It's as simple as that. It has nothing to do with configuration. If you don't believe me, write a simple php code to see if it is millisecond waitting
