Eaglercraft 112 Wasm Gc [2021] May 2026

WASM-GC

Eaglercraft 1.12 with (WebAssembly Garbage Collection) represents a major shift from traditional JavaScript-based browser ports. By using a native binary format that manages memory more efficiently, this version achieves near-native performance for a Java-based game like Minecraft 1.12.2. Overview of Eaglercraft 1.12 WASM-GC

Benchmarks from community testing (Eaglercraft 1.12 pre-release vs 1.8 JS version): eaglercraft 112 wasm gc

The Technical Challenge: Why 1.12 is Hard

Conclusion

Performance Benchmarks (Real World)

• Java 17 JDK
• Binaryen (for WASM GC optimizations)
• A recent version of TeaVM with WASM GC backend (or the Eaglercraft fork)

• Metrics to collect: frame time, JS-Wasm crossings per frame, allocation rate (objects/sec), GC pause times, memory footprint, network latency for deserialization.
• Hypothesis: For heavy object-focused workloads (chunks, entities), Wasm GC can reduce per-tick CPU overhead by 15–40% vs. linear-memory object emulation and reduce JS glue.
• Validate with microbenchmarks (allocation/collection), mid-level tests (chunk generation), and full-play tests.
