Observable profiles (tile) entities and shows you what's taking up tick time and where. Forge and Fabric compatible. Please report any bugs on the GitHub repository here.
(Note: the default keybind to open profiler GUI is R.)
Current known issues:
- Results screen is sometimes empty (closing and reopening the GUI fixes it)
FAQ:
- Why is the mod crashing on startup with a "java.lang.NoClassDefFoundError: kotlin.jvm.<whatever>"?
The mod uses the Kotlin standard library, so please install a mod that provides that, such as Kotlin for Forge or Fabric Language Kotlin.
- Does this mod need to be installed on the server?
In order to work, yes. Also, players can connect without the mod installed on the client, however they will not be able to use any of its features.
