Soft rejection. Need Help Pls

I got a soft rejection twice because of the demo performance not up to the mark. I understand that I will need to improve but things seem to be very fast for me. I am aware that the page is content heavy. Please let me know how the demo loads for you.
Demo link :

These were the feedback that I got

First attempt

  1. Check your demo. Never finishes loading: https://envato.d.pr/G1NZzL

Second attempt

  1. Ok, retested and it finally loaded but took quite some time.

Please improve the demo performance.

This my recording in real-time it seems to load quickly: https://youtu.be/JN8y28_Llpc

It is on a good server also currently I have turned off any caching. Also, I have a 50Mbps connection.

Please help. How does it load for you?

Thanks

Loads here, check your gtmetrix

12seconds is waaaaayyy too slow in current days. Aim for 3s or less

Thank you @crivion. But It’s having a lot of content. Total page size is around 6 MB + heavy youtube scripts. It was intentionally kept slower to show all the possible solutions by my plugin. Should I split the content? and have thumbnails.

I think Making separate pages for a set of features would be a solution

Thank you let me work on it.

You’re welcome - these are just my thoughts. Doesn’t guarantee that you’ll get approved.

Making separate pages for a set of features is definitely a great solution.
