No Performance Only Lag
by Alex1177
No Performance Only Lag is a NeoForge cursed mod for 1.21.1 whose lag command, after a 5-second delay, can crash the game.
What it does
Running the lag command in No Performance Only Lag triggers a deliberate slowdown that the author describes as possibly crashing the game after five seconds. The mod is aimed at modpack testing and joke use rather than real gameplay, and the author notes it works better alone than inside a modpack.

What the author says
This mod adds the "/lag" command that gives an effect, that after 5 seconds or after the effect expires, it summons so much dropped items and so much particles it will crash your game before the particles and dropped items could be seen by the player. This mod is better alone rather than in a modpack. But do as you…
