Performance & Benchmarking Standards

Set up Criterion.rs benchmarks in your Rust CI/CD pipeline to measure latency and throughput automatically, detecting performance regressions before they reach production.

The best way to profile Rust code for bottlenecks is using cargo-flamegraph and perf, which visually map execution time to specific functions and identify exact performance bottlenecks.

To set up Criterion.rs benchmarks, implement your performance tests in the `benches/` directory of your Rust project, enabling detailed analysis of latency, throughput, and memory usage for critical code paths.

Optimization patterns that improve memory efficiency in Rust include zero-copy patterns, buffer reuse, and efficient string handling, which minimize allocations and reduce overhead during execution.

You should run automated performance tests on every code change in your Rust project, ensuring that performance regressions are caught early in the CI/CD pipeline rather than after reaching production.
