In the recent update 1.18.31 the game mechanics are very delayed when opening chests takes a long time, when there are enough mobs nearby they start to move slowly and they delay all mechanics, be it eating, opening chests, getting out of the water, throwing projectiles etc.

The internet signal has nothing to do with this probability since playing in 1 player mode the game is still delayed when eating. You eat and the hunger bar doesn't fill up and the item doesn't consume you either. (he emphasized that I am not referring to the FPS of the game, that is still fluid).
