+🌊 Water HTTP — TechEmpower Benchmarks
+
+Water HTTP is a high-performance Rust web framework built and optimized for the TechEmpower Framework Benchmarks (TFB)
+. It is designed to push the limits of speed, stability, and scalability using pure asynchronous Rust and Tokio’s runtime. Every part of the framework is hand-tuned to achieve predictable latency, minimal allocations, and efficient CPU utilization under extreme concurrency.
+
+This repository contains the official benchmark implementations for all test types, including Plaintext, JSON serialization, Single query, Multiple queries, Fortunes, Database updates, and Cached queries.
+
+⚡ Highlights
+
+🚀 One of the fastest and most stable frameworks in the TechEmpower Benchmarks
+
+🧵 Built entirely on Tokio’s asynchronous runtime — no io_uring or unsafe code
+
+💾 Zero-copy I/O, preallocated buffers, and predictable memory layout
+
+🔒 100% safe Rust with no hidden synchronization overhead
+
+🧱 Designed for consistent high performance at scale
+
+
+🧠 Architecture
+
+Water HTTP is built around a fully asynchronous, event-driven architecture that leverages non-blocking I/O and efficient request processing. The system is designed to eliminate unnecessary locks and minimize latency even under heavy load.
+
+[ tokio::net::TcpListener ]
+         ↓
+   [ connection handler ]
+         ↓
+   [ water::http::parser ]
+         ↓
+   [ application logic ]
+         ↓
+   [ response encoder ]
+This approach ensures optimal throughput and minimal per-request overhead while keeping code simple and safe.
+
+
+🧭 Mission
+
+Water HTTP’s mission is to demonstrate how Rust’s async ecosystem can reach record-breaking performance without compromising simplicity, safety, or maintainability. It shows that carefully engineered async Rust can deliver unmatched speed and reliability in real-world workloads, setting a new standard for what modern web frameworks can achieve.
