The Nether is Laggy on PS4

My game is extremely laggy in the nether on PS4. On my iPad the game run smoothly in the Nether. It still a little bit laggy in the overworld but way less than in the nether. It a solo world and my connection it’s pretty stable. Minecraft seen to be the only affected in my console ans my storage still have a long of memory. It seem that ghast make the game instable.
