To find Rust performance bottlenecks, you should measure first using cargo bench and generate a flamegraph to identify hotspots before applying targeted optimizations like reducing allocations or improving cache locality.

The best way to benchmark Rust code is using criterion with cargo bench to establish measurable baselines, which helps quantify performance and ensure optimizations yield repeatable results without regressions.

Yes, flamegraph helps analyze CPU hotspots, while specific memory and cache optimizations in Rust involve techniques to reduce allocations and improve data locality based on those profiling measurements.

To scale CPU-bound Rust workloads, you can apply parallelism and concurrency using rayon or multithreading after establishing a baseline with cargo bench to verify the performance improvements.

Yes, measurable baselines are required before optimizing a Rust binary to ensure a disciplined workflow where you pinpoint hotspots first and apply targeted optimizations that yield repeatable results.

Flamegraph may be limited if you lack measurable baselines from cargo bench, as profiling requires established toolchains and quantifiable data to accurately identify hotspots and apply targeted optimizations.
