Slow first access to a website

I install last open cyberpanel and configure this correctly.
The problem is that first load of a website is very slow.

Please test here:

install ssl so its running on h2, but its loading fine for me on first load.

Already installed ssh

The page load on ssl is fast, there is a delay on non ssl

If you see response headers first request is always a cache miss, and subsequent requests are then cache hit.

That is why you feel the difference, however if difference is too big in seconds then there can be some issue. Because it is just a plain WordPress site.
