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.
