Lag Generator

This is a simple, brute-force "lag" generator for Minecraft servers.

It is configured via game rules.

• lag_generator_enableLag, true or false (false by default)
• lag_generator_serverPreTickLag, integer value of lag (in milliseconds) that should be created in each server pre-tick (default 80)
• lag_generator_serverPostTickLag, integer value of lag (in milliseconds) that should be created in each server post-tick (default 80)
• lag_generator_entityTickLag, integer value of lag (in milliseconds) that should be created in each entity base tick (default 10)

Lag comes in three flavours:

• Server Pre-Tick lag is added with Thread.sleep at the start of each server tick (after the tick count has been incremented)
• Server Post-Tick lag is added with Thread.sleep at the end of each server tick (after the profiler has been popped)

Both of these types of lag statically decrease TPS.

• Entity tick lag is added with Thread.sleep in the Entity::baseTick method.

This type of lag is cumulative depending on the number of loaded entities.
