Why does my Site render so slowly on Safari?

Question

I am working on the following Site: https://fsa.thewire.ch It's been working smoothly on Chrome. Now I have tested it on Safari and 1. the site loads more slowly and 2. and more importantly, the site only renders a little bit more than what is in the viewport. When I scroll through the page "quickly" it takes a while to load the content. I'm using a landing image with a $(window).load function but safari doesn't seem to care about that. I don't experience the issue on other pages and my page is not extremely heavy. Also, the network tab doesn't show any issues. What do I have to change?

Answer 1

Some jpg files, a svg file and this js: https://fsa.thewire.ch/wp-includes/js/wp-emoji-release.min.js?ver=5.4 spend a lot to be downloaded. In some Safari configurations this can be a problem. Try to resize the jpg files and check why this js file spend a lot of time to load

are you using wordpress?
