Slow load time on mobile

Hello,

I have a page with 41 video. Videos on Yb and I inserted them to the Media Library.

The problem is:

When I open the page on my phone, I have to wait many seconds for all the Presto Players to load with the videos.

No such problem on a computer, but we have tried it on several phones and it is slow there. At first there is just blackness on the player site, then it loads one by one. It has LiteSpeed cache and the storage is good.

Previously we used another plugin to embed hundreds of videos on one page (defer video) and then we didn’t have this problem. With Presto it’s significantly slower.

We imagine that both the video and the player should only load when someone clicks on it, not before. Does the player not know this?

If we put 100 videos on a page, all with Presto, will the page be very slow?

Also, I tried this by loading videos from Vimeo, not Yb.

It’s even slower that way, it’s like the videos are loading in the background, but I guess they shouldn’t. https://www.lakatoszsanett.com/vidttvimov/

You can check it, if you press F12 and check network.

Thanks.
