The more screen elements are for each screen, the slower it works. I had 1000 screens with one element and it took about 39s to load before and after, so no changes in performance was visible. When I added 100 screens with each one having about 100 elements, it just crashed while opening the page. Once I got it to open after 490s, but with this fix the page opens in 32s, so indeed the fix is good and works. Good work! TESTED |
