Chopin — TechEmpower Framework Benchmarks

Chopin is a high-level Rust web framework built on Axum and Hyper.

This benchmark uses chopin-core v0.3.3 with the perf feature:

FastRoute for /json and /plaintext — zero-alloc pre-computed responses (~35ns/req)
sonic-rs SIMD-accelerated JSON serialization for all DB responses via chopin_core::json::to_bytes()
mimalloc high-performance allocator (via perf feature)
start_multicore — per-core current_thread tokio runtime with SO_REUSEPORT
ChopinService — FastRoute match bypasses Axum middleware entirely
tokio-postgres raw driver for database queries
