# Rust Performance

> - Rust performance — measure-first methodology, benchmarking (criterion/divan), profiling, concrete optimizations (build config, allocations, hashing, type sizes, iterators), and cutting compile times. Use when code is slow, optimizing a hot path, choosing a profiler, or when builds are slow. Triggers: criterion, divan, flamegraph, FxHashMap, LTO, PGO, jemalloc, dhat, compile times, mold, sccache.
