I transferred my world over from the old Minecraft xbox one edition, it was a super flat world however it was pretty big and filled with lots of buildings. So I transferred it to the newer Minecraft. When I loaded my world up on Minecraft the world seemed fine but when I tried going on minecarts and it was super slow to the point where I could walk faster than them, redstone took ages to be activated, tnt took ages to explode and when I tried using splash potions they took ages to be thrown and just sort of lagged mid air. My world isn't a relm. And everything works perfectly back on the old Minecraft. I created a new world on the newer Minecraft which is currently at V1.14.60 and everything works fine including the problems I mentioned above. So I was wondering if there is anything I can do to stop my transfered world from lagging as most of my builds on my world are made from redstone.
