FAQPage Schema

How do I set up a BenchmarkDotNet project to measure .NET performance?▼

To measure .NET performance with BenchmarkDotNet, create a minimal project, annotate a method with [Benchmark], and run it to capture per-operation timing. Proper project setup includes selecting common job configurations and target runtimes.

What is GlobalSetup used for in BenchmarkDotNet microbenchmarks?▼

GlobalSetup in BenchmarkDotNet microbenchmarks is an enforced usage pattern used to execute initialization code once before benchmark iterations begin, ensuring accurate performance measurements by isolating setup overhead from the actual method being measured.

How do I compare .NET performance across different runtimes and build configurations?▼

You can compare .NET performance across different runtimes, input scales, and build configurations by applying recommended BenchmarkDotNet job presets to execute benchmarks side-by-side and interpret the exported timing results.

Why should I avoid inner loops in .NET microbenchmarks?▼

Avoiding inner loops in .NET microbenchmarks is a required design pattern because BenchmarkDotNet automatically handles iteration counting to ensure accurate per-operation measurements, and manual loops skew the timing data.

Can I parameterize input data in BenchmarkDotNet to test different performance scales?▼

Yes, you can parameterize input data in BenchmarkDotNet to test different performance scales. Proper input parameterization is an enforced usage pattern that allows you to measure how methods perform across varying data sizes and scenarios.

What is the best way to export BenchmarkDotNet results for performance analysis?▼

The best way to export BenchmarkDotNet results for performance analysis is to apply the benchmark configuration patterns that automatically generate output reports, enabling side-by-side comparisons across approaches and input scales.
