It's loading pretty fast for me - can you please check your current internet connectivity speed?
Best of luck!
Your collections are loading slow for me too. Are there is product images that have a file size that is to big? All it takes is for one image to be to large on a page for it to load slow. Have you tried reducing the number of SKUs / page and see if that decreases the load time?
If images are not your issue, then I would disable any 3rd party apps you are using and see if that speeds things up. Only activate one app at a time and see how your page speed is then. I checked out a few product pages and even those took an extra second to load for me. Here are some ways I thought you could improve your product page and increase sale:

Hope you found this helpful, if so please click "like" below to let me know. You have a great site, so once you sort out page speed... you should be off to the races.
This is an accepted solution.
No way, it takes around 10 seconds every time I click on a collections page.
Go from one collection to the other and see how fast that loads
You have something called 'discount manager' likely is the cause for slow loading.
This can hurt your sales badly.
You have enormous network payloads. I think your images are too big and/or not the proper file extension. Try WebP instead of JPG, this should do wonders for you.
