## TL;DR

- **vs pgbouncer** — pg_doorman peaks at **x12.0** TPS on prepared protocol, 120 clients.
- **vs odyssey** — pg_doorman wins by **+40%** at most (extended protocol, 120 clients).
- **Tail spread at 10 000 simple-protocol clients** (`p99/p50`, lower = more predictable) — pg_doorman 1.1× (59.9→64.5ms), pgbouncer 1.4× (276→387ms), odyssey 11× (17.9→204ms).
- **vs pgbouncer** — pg_doorman peaks at **x9.7** TPS on prepared protocol, 500 clients.
- **vs odyssey** — pg_doorman peaks at **x1.5** TPS on extended protocol, 10,000 clients.
- **Tail spread at 10 000 simple-protocol clients** (`p99/p50`, lower = more predictable) — pg_doorman 1.3× (39.2→51.6ms), pgbouncer 1.3× (278→367ms), odyssey 116× (2.60→301ms).
