performance-and-benchmarking-standards

To detect performance regressions in a Rust CI/CD pipeline, integrate Criterion benchmarks to automatically track latency and throughput changes across builds. This catches degradation automatically during continuous integration.

The best way to profile Rust code for CPU and memory bottlenecks is using cargo-flamegraph, perf, and Instruments to generate flamegraphs for detailed performance analysis and allocation tracking.

Set up Criterion.rs benchmarks to measure throughput by configuring benchmarking suites that track latency, throughput, and memory allocations, enabling precise detection of performance regressions in Rust applications.

Implementing zero-copy patterns and buffer reuse in Rust improves memory efficiency by minimizing unnecessary allocations. Combined with allocation tracking, this optimization significantly reduces memory bottlenecks.

Use cargo-flamegraph to visualize Rust call stacks as an interactive flamegraph, whereas perf provides lower-level CPU and memory analysis. Both identify bottlenecks but offer different granularity for profiling.
