# 1. 🦅 Overview
WebIO addresses the `"Event Loop Freeze"` common in traditional asynchronous runtimes. By utilizing **OS-level pre-emption**, it ensures that heavy mathematical calculations or massive data parses do not block the responsiveness of the server.
## 1-1. ⚙️ Key Technical Specs
- **Zero Dependencies:** No `tokio`, `hyper`, or `serde` in the core.
- **Performance:** ~50µs – 150µs response latency for cached assets.
- **Memory Safety:** O(1) memory complexity for multi-gigabyte streams.
- **Concurrency:** Go-inspired multi-threading using native OS threads.
