Key Takeaway (TL;DR): Sing-box is the most performant next-generation universal proxy core. Moving away from legacy YAML architectures, it features a native JSON schema and zero-copy routing pipeline with built-in VLESS Reality, TUIC v5, and Hysteria 2 support. It cuts memory usage to 35% of legacy Clash while improving single-thread network throughput by over 20%.
1. Architectural Highlights
- Native modern protocol implementations without external binaries.
- Binary rule-set compilation (.srs) for instant routing queries.
- Clean JSON schema dividing inbounds, outbounds, DNS, and routing rules.
