Engine · C# · engine: io_uring
Hand-rolled WebSocket echo on the Minima engine — a from-scratch C# multi-reactor io_uring server (direct io_uring syscalls via libc, multishot accept + multishot recv into a provided buffer ring, one ring per core with SO_REUSEPORT). The RFC 6455 handshake and the frame parser/masking/echo are written by hand on Minima's raw recv/send API; no WebSocket library.
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. The field is this entry's own league: engines and reverse proxies are scored apart from frameworks. How it works.
| Family | Rank | Composite |
|---|---|---|
| WebSocket | 6 of 9 | 188 |
Every result
Alpha Round, 6 runs. Requests per second is the best of three; latency, CPU and memory come from that run.
