Legacy Profiler

Legacy Profiler is a lightweight developer profiling API for Minecraft Forge 1.7.10.

It gives mods a shared way to measure performance without each project needing to implement its own profiler, report system, or session handling.

Integrated mods can register named timing stages, counters, and events. Server operators can then start and stop profiling sessions with commands and export the results for analysis.

Features

• Shared profiling API for Forge 1.7.10 mods
• Named timing stages and counters
• Thread-safe recording for concurrent workloads
• Session and stage attribution
• JSON, CSV, and readable log exports
• Validation warnings for incorrect timing usage
• Designed for profiling systems like world generation, chunk loading, caches, and tick processing

Profiles are exported to:

profiles/legacy-profiler/

Commands

• /legacyprofiler start
• /legacyprofiler stop
• /legacyprofiler status

For Players

Legacy Profiler is not an optimization mod by itself. It is primarily a developer and diagnostic dependency used by compatible mods to collect detailed performance information.

If another mod lists Legacy Profiler as a dependency, install the Legacy Profiler JAR separately in your mods folder.

For Developers

Consumer mods register their own profiling stages and record observations through the public API. Legacy Profiler handles the shared runtime, session lifecycle, validation, and report generation.
