ringzero-ws
Engine · C · engine: io_uring
Hand-rolled WebSocket echo server on raw io_uring (liburing) — no WebSocket library. Multishot accept + multishot recv into a provided buffer ring for zero-copy ingest, one ring per core with SO_REUSEPORT, and a from-scratch RFC 6455 handshake (hand-written SHA-1 + base64) and frame parser/masking.
Achievements
🥇 1 Gold · 🥉 2 Bronze. Top three of a field, taken in this entry's own league: the family composite, the same composite among entries written in the same language, and each test profile it is scored on. Every field is the one the badges publish, so a medal and a badge always say the same thing. How medals are awarded.
| Medal | Award | Field | Rank |
|---|---|---|---|
| 🥇 Gold | Test profile | WebSocket · Echo Pipelined | 1 of 8 |
| 🥉 Bronze | Family composite | Composite · WebSocket | 3 of 9 |
| 🥉 Bronze | Test profile | WebSocket · Echo | 3 of 9 |
Composite rank
Each profile of a family is worth 100 to the entry that leads it, and the composite is the sum over the family, less 2.5% for each of routing, middleware, request and response the entry does not do for you - its completeness factor, which the WebSocket and gRPC families do not carry. The field is this entry's own league: engines and reverse proxies are scored apart from frameworks. How it works.
| Family | Rank | Composite |
|---|---|---|
| WebSocket | 3 of 9 | 1988 |
Every result
Alpha Round, 6 runs. Requests per second is the best of three; latency, CPU and memory come from that run.
