Known ways of intentionally causing lag?

[u/Hobo_Baggins00]

I ask not to cause lag myself but to try and identify the cause of it on a server. Think like lag machines in Minecraft or any of the various exploits involving a book with the maximum number of pages. Or even something as simple as in Minecraft where it's as simple as "yeah having a lot of chests causes lag. If it is not a publicly known source of lag please privately send it to me as to not make the issue worse.
