I have a lot of loading time in my Joomla websites. The idle time is over 2 sec. On the website I have 125 SQL queries. I use Helix Ultimate with the SP Pagebuilder Pro Link to my Website: http://www.wawi24.net/
I checked your website, you have messed up image urls. Below is the list of images your website is trying to load but failing and adding to the unwanted load time. Recheck your urls and you'll definitely see a increase in response time.

Ok so there are a couple of issues here
- Time To First Bye (TTFB)
- General performance
So, firstly, you're going to want to get your hosting providers to install a free SSL cerificate (Let's Encrypt) which will utilise HTTP/2.0 and improve the speed at which assets are fetch from the server.
The TTFB is something you hosting provider is going to have to look into. That said, sometimes it's simply a matter of where the datacenter is. For example, if you live in Europe, don't use a hosting provider in the US or Asia, simply because they are further away and the latency will be a lot higher.
Try using the LightHouse speed test with Google Chrome as you gradually make improvements
