EventBenchmark

by CarbonMC

EventBenchmark is a Forge and NeoForge utility that measures how fast the game's event bus handles listeners and published events.

ForgeNeoForgeClient or server, optionalMIT LicenseOpen source1.20.1 – 1.21.1

What it does

Three commands drive the benchmark: one registers 10,000 listeners, another registers 1,000 listeners and publishes 10,000 events, and a reset command removes the listener registrations afterward. The results show how the event system behaves under that load. Files are published for Forge and NeoForge against 1.20.1, 1.21 and 1.21.1, and the code is open source under the MIT License.

Only the client or server needs the mod, and neither side requires it, so it can be installed for testing alone. The source code and issue tracker are public.

Key features

  1. Listener registration test

    A command registers 10,000 event listeners so the event bus can be timed under a large number of subscribers.

  2. Event publishing test

    A second command registers 1,000 listeners and publishes 10,000 events to measure dispatch throughput.

  3. Listener reset

    A reset command clears the registered listeners so that tests can be run again from a clean state.

Questions

Does EventBenchmark need to be installed on a server?

Not necessarily. Either side can run it, and neither needs it, so installing it on the client alone or the server alone is enough.
