I can't see any issues there that could be causing it it could possibly be rapid chunk loading or just there's currently a bug that makes some users experience lag spikes honestly I can't think on what it could be.
Can I have a screenshot of the debug screen
What OS are you using and how often do you get this error
Can you send any screenshots with the debug screen and it could be an entity placement bug or player position bug for the moving issues
Could it be your computer rather than the game?
Can I have a screenshot of the debug screen?
Could I have an image of the debug screen please
If you hear a bark like a dog there's probably a entity of a dog around and the lag could be caused by your iron farm
