I have a huge area of Command Blocks on my adventure map that function with a tickingarea.
Before the Hotfix Update 1.20.31 my world had a pretty good performance. After the update however, after the 1.20.31 Hotfix. My world has gotten realy laggy. I tried it without the tickingarea aswell. The world runs smoothly outside the command block zone. But lags horribly as soon as i entered it. This has not happened before the Hotfix so my best guess is that it's caused by the Hotfix. A bit of lag is still understandable, but in the current state i can even keep a mob above my head in the air by just punching it. This also affects the tickrate and makes many comand block contstraptions based on tick delay very buggy. I would apreciate if the lag caused by comand blocks could be reduced to a minimum.
Thank you,

UPDATE: This Issue is only as bad as i described it when another player is on the world.
