Subject: [PATCH] Configurable Max Chunk Gens per Tick
|
|
|
|
Limit the number of generations that can occur in a single tick, forcing them
|
|
to be spread out more.
|
|
|
|
Defaulting to 10 as an average generation is going to be 3-6ms, which means 10 will
|
|
likely cause the server to lose TPS, but constrain how much.
|
|
|
|
This should result in no noticeable speed reduction in generation for servers not
|
|
lagging, and let larger servers reduce this value according to their own desires.
