Repeater- causing crashes or extremely slow

I have been working on my dog walking website.
But it is extremely slow on my " adventure map " tab, it takes about 30secs to load or if i am editing the site I can’t even preview that page because it crashes and I have to close the page as it won’t load anything…I even left it for over a hour once.

Currently there at x46 items in the datasheet, is this too many or is there a way to fix this?
Not sure if it helps but I dont have any coding just the sheet provided (pic below)

Thanks in advance.

Hi Dean,

That is a lot of items to load at once, I would suggest setting up a pagination bar or a show more button.

Hi Joy,

Thank you, I will try both and see what works best.
