suggestion: stop ticking chunk if chunk causes lag

Seems like a common-sense measure on paper, but I don't know how that can theoretically be detected. You might be able to create an "activity frequency" for each chunk low-level based on what events are triggered by a chunk, and if the frequency grows too rapidly (compare the frequency between ticks) or the frequency is just too high then you can stop ticking the chunk. Depends on how low-level the developers are willing to go though, although if there is a higher-level way than what I described or just an easier way then that can be done instead. Might even be able to reset the chunk automatically if there are too many activities.

You are correct that most lag machines are not larger than 16x16, but that doesn't mean they will be in a single chunk because you can align them with the chunk borders in any way you want. You could even build lag machines in such a way that you stay below the threshold of each individual chunk, but the total machine still causes lag. However, that might be too advanced for the people we want to counter with this.

As for the actual method of stopping the lag, I have a feeling that stopping the ticking of a chunk that is in the middle of active terrain leads to glitches so weird that you end up in a "the cure is worse than the disease" situation. There are milder forms of reducing the activity in a chunk, though. Resetting chunks (as suggested by Wilee) just seems like a great way to grief entire chunks at once to me.

It depends on whether you want the server to be alive but a certain chunk to be reset or the server to be offline but with the chunk intact, depending on the severity. You can also go even further low-level and reset certain blocks, it's not impossible.

you are correct but i think most people who bring lag machines on the server won't think to put it inbetween chunk borders, correct me if im wrong tho

There's a plugin I used to use for my server that does exactly this. You can view any chunk that may be causing lag and teleport to it.
Here's the plugin: www.spigotmc.org/resources/lagassist-%E2%9A%A1-advanced-performance-solution-%E2%9A%A1-1-8-1-15-compatible.56399/
Highly recommend.

I've already payed the 10 euros, if you want it just hmu on discord.
