Question 1

How to integrate Nonius into a CMake project?

Accepted Answer

Since Nonius is header-only, you can simply include the header file in your source code. Add the header path to your include directories in CMakeLists.txt, and ensure your benchmarks are compiled with appropriate optimization flags for accurate timing.

Question 2

Nonius vs Google Benchmark for C++ micro-benchmarking?

Accepted Answer

Nonius is header-only and inspired by Criterion for statistical rigor, making it simpler to set up but with a smaller ecosystem. Google Benchmark has more features, better documentation, and wider adoption, but requires building and linking.

Question 3

Can Nonius benchmark multi-threaded code?

Accepted Answer

The README doesn't specify, but as a micro-benchmarking tool focused on small snippets, it may not natively support multi-threading. You'd likely need to handle thread management manually within benchmark functions.

Question 4

What statistical methods does Nonius use for analysis?

Accepted Answer

Inspired by Criterion, it likely uses techniques like bootstrapping or confidence intervals to analyze timing measurements, but the README lacks specifics—refer to the source code or documentation for details.

Question 5

Is Nonius suitable for benchmarking large functions or only small snippets?

Accepted Answer

It's specialized for micro-benchmarking small, isolated code, so for large functions, the overhead and statistical methods might be less effective; consider using tools designed for macro-benchmarks instead.

Question 6

How to handle outliers in Nonius benchmarks?

Accepted Answer

Nonius performs statistical analysis to account for variability, but you may need to configure parameters or inspect raw data manually, as the README doesn't detail outlier handling mechanisms.
