Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 1520, "days_push": 764, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A benchmarked guide of Java flags and JVM tweaks for optimizing Minecraft client and server performance, with a Python benchmarking script to validate each flag. It also covers choosing Java runtimes like GraalVM, Adoptium, and Clear Linux OpenJDK.

## Use cases
- reduce stutter in modded Minecraft
- tune JVM flags for a Minecraft server
- pick the best Java runtime for Minecraft
- benchmark Java garbage collectors for Minecraft
- get better TPS on a modded server
- optimize Minecraft FPS with Java arguments

## When to choose
- you run a modded Minecraft client or server and want tested JVM flags
- you want evidence-based Java runtime and GC recommendations for Minecraft
- you want to benchmark flag changes yourself with the included script

## When to avoid
- you expect large FPS or TPS gains from flags alone
- you need to fix lag caused by mods rather than JVM overhead
- you use OpenJ9 or non-OpenJDK runtimes with incompatible flag sets
