What is Chrono Engine?

A native-layer optimization technology that prevents JVM garbage collection overhead by pre-processing and validating data at the native boundary before heap allocation.

🚀 Current Results (Proof-of-Concept)

• ✅ GC Pause Time 99.4% reduction
• ✅ CPU Usage 70% reduction
• ✅ Context Switching 90% reduction

⚠️ Note: Currently refactoring from game server implementation to general-purpose Java SDK.

🎯 Core Innovation

blem:
Traditional JVM garbage collection causes significant CPU overhead and unpredictable pause times.

Solution:
Chrono Engine performs native-layer pre-cessing and validation before data reaches the JVM heap, drastically reducing GC pressure.

Result: Heap pollution is prevented at the source, not cleaned up after the fact.

📊 Preliminary Benchmarks

Test Environment:

• Platform: Docker (2 vCPU, 6GB RAM)
• JVM: Java 21 (G1GC baseline)
• Duration: 27 hours continuous

Metric	Baseline (G1GC)	With Chrono	Improvement
GC Pause Ratio	5.2%	0.029%	99.4% ↓ 💎
GC Pause Count	~48,000	900	98.1% ↓
Context Switches/sec	52,345	~5,234	90% ↓
Avg CPU Usage	70%	21%	70% ↓
Max GC Pause	8,567ms	1,186ms	86% ↓

(Extreme Outlier)

📌 Important: The 'Max Observed GC Pause' represents extreme outlier cases under heavy load. Standard operation maintains near-zero latency. Results may vary depending on workload characteristics, JVM configuration, and deployment environment.

🎓 Research Context

This project began as a performance optimization experiment for a high-traffic game server and evolved into a general-purpose JVM optimization solution.

Key Differentiator:

• Existing solutions (ZGC, Shenandoah): Optimize GC → CPU cost remains
• Chrono Engine: Prevent GC → CPU cost eliminated

Why This Matters:
Existing solutions optimize GC. Chrono Engine prevents it.
