ankerl::nanobench is a single-header, platform-independent microbenchmarking library for C++11/14/17/20. It measures ns/op, op/s, instructions, cycles, IPC, and branch misses with fast, accurate, repeatable results.
Use cases
- benchmark small C++ code snippets
- measure nanoseconds per operation in C++
- compare performance of C++ implementations
- profile instruction counts and branch misses of hot code
- add microbenchmarks to a C++ project with minimal setup
- replace google benchmark with a faster, header-only alternative
When to choose
- you need quick, accurate microbenchmarks in C++ with zero build complexity
- you want a single-header library that integrates via CMake FetchContent or direct inclusion
- you need detailed metrics like IPC and branch prediction misses
When to avoid
- you need full application profiling rather than microbenchmarking
- you are not working in C++
- you need distributed or long-running benchmarking infrastructure
