Multiple status effects cause the game to lag only in survival mode

I am not a native English speaker so my writing might be unclear, I apologize for that.

I created an armor that adds several status (potion) effects to the player, and it works fine.

However, when I switch the game mode to survival, it makes the game to lag and drops FPS to like 10. 

It works perfectly in creative mode(FPS is fine), and the event trigger is not even "on entity tick update" but instead equipping the item, which means the procedure to add potion effect is executed only once, so I have no idea why this terribly affects the game performance only in survival.

I appreciate any help.
