Hi and welcome to the forum
For a WP site it is to be expected to be slower
also, you are quite far from the server, so you can expect additional latency
but it’s nothing extra dramatic (click me)
You need to optimize this file cropped-8.png because it takes 3 seconds
and you have a lot of JS files
Please see the waterfall view here https://www.webpagetest.org/vitals.php?test=231228_BiDc0N_DX0&run=3
It is possible that they experienced this
Your website is not extra complex (some text and lazy load images)
there are not many PHP processes in the background (a bunch of plugins and the like).
As far as I can see, you use hivepress as a plugin
and I don’t think it would be a big problem to serve 50 users (of course if they don’t exceed your hits limit (I put the link above under limits)…
There are just too many HTTP REQs and it’s up to you to optimize it a bit - that the page loads faster.
Ideally, you should not use WordPress (PHP) but have a static website (HTML - then it would be the fastest)
