Loading takes 10 seconds, extra config needed?

[sanderdatema]

When using Caddy my sites load pretty fast, but with NginxPM it takes about 10 seconds for each first load. After that it's ok. But when I wait a few minutes, it'll take a few seconds again.

Am I missing something?

The admin site isn't 100% optimised and it might be that it's JS assets aren't cached. Or it might be that the database isn't warm. Open your web browser's dev tools and see which parts (js or xhr) are taking the longest to respond.

The weird thing is that the first 10 seconds absolutely nothing happens. Only after that the browser is able to request anything. Like a dns request that takes ages. Except that it can't be that, because Caddy works fine.

It's not just your admin site, it's any site.

Is there a debug setting I could use?

If it is a DNS issue you can test by opening a console and trying to lookup a record and see how long it takes:

nslookup www.google.com.au

Try different domains you've probably never visited, to make sure you're not using your local dns cache.

But that's what I said: it's not a dns issue, Caddy would have trouble too, then.

Edit: somehow Wordpress caused this. Other sites did load fine. So, it's solved.
Thanks for taking the time to look into this.
