Elysia 2 vs Django 6.1, One Process Each: 14–21x per CPU-Second

We ran one seven-route API on Elysia 2 (Bun) and on Django 6.1 with Ninja, sync under Gunicorn and async under Uvicorn, one process each. On the four database routes at c=100 Elysia served 14.1–21.5x as many successful requests per CPU-second as sync Django. Async Django fell 12.6–16.2% behind sync at 500 connections, Django won the hash loop, and the runs that broke before this one are here too.

Elysia 2 vs NestJS 12: Runtime +64.6%, Framework +10.6%

We moved one API from NestJS 12 on Node to Elysia 2 on Bun one layer at a time. On the database routes the runtime step bought +64.6…+81.5% throughput and the framework step +7.5…+12.7%; Elysia's own wins are memory and boot. The friction, the contention story and the hosting bill are here too.
