## AI overview

The article benchmarks cold startup times for Encore.ts, Fastify, NestJS, and Express using API endpoints and schema validation. It reports that Encore.ts started over five times faster than Express and over 17 times faster than NestJS in the tested setup, and explains why cold-start latency matters for serverless and distributed systems.
