Forge profiler
by TroubleGy
Forge profiler is a performance profiler for Minecraft 1.20.1 that reports memory use, FPS and tick times from chat commands.
What it does
Readings for server and client tick times, memory use, FPS and world generation speed are displayed live, as the profiler collects them. Output appears in chat as compact, colored lines, and a single command clears the stored logs. An automatic log cleaning mode keeps the log folder from growing without limit.
Server owners, modpack builders and players looking to keep a 1.20.1 install stable are the audience this profiler is written for. It is built on pure Forge events and mixins, which the author describes as a route to maximum compatibility with other mods. Only Forge is supported, and files are published for 1.20.1 alone.
Forge profiler runs on client and server, so both the server and every player need it. It is released under the MIT License and is not open source. Files exist for Forge 1.20.1 only, with version 1.0 dated 2025-07-05, which is also the first and last update.
Key features
Memory monitoring
Memory usage is tracked while the game runs and can be read from chat at any time.
FPS and tick timing
Frame rate and tick times are reported in real time for both server and client.
World generation timing
The time spent generating world chunks can be measured to find slow generation.
Single-command log clearing
Stored profiling logs are removed with one command instead of being deleted by hand.
Automatic log cleaning
An optional mode removes old logs on its own so the log folder stays small.
