Version terminology

Core

The main Slimefun plugin that provides APIs, items, Guide systems, storage and runtime infrastructure.

Fork

A separately maintained codebase derived from another project. Slimefun Legacy is an unofficial downstream fork of Slimefun 4.

Upstream

The project/codebase from which a fork or dependency originates. Because Slimefun has multiple community continuations, "upstream" can depend on context.

Candidate

The Slimefun Legacy build currently being tested for a future release.

Performance terminology

TPS

Ticks per second. Minecraft normally aims for 20 TPS.

MSPT

Milliseconds per tick. This is often more useful than TPS when investigating how close a server is to falling behind.

Profiler

Tool that records where server time is being spent. Slimefun's /sf timings provides Slimefun-specific information; spark is commonly used for server-wide profiling.
