About
Criterion.rs runs Rust benchmarks with warmup, resampling, confidence intervals, and regression comparisons. It produces readable reports and integrates with Cargo for repeatable code-performance experiments.
Best for
Repeatable method, function, and command runtime benchmarks
Teams that prefer open-source licensing and self-hosting options
Groups comfortable scripting in Rust
Not the best fit when
Teams unwilling to operate generators, results storage, and scaling
Architecture and concurrency
Criterion.rs is operated as a code benchmark harness with Rust. It isolates functions, methods, or commands and applies repeated measurements, warmups, and statistical comparison rather than generating protocol traffic.
Criterion.rs is best for developers measuring the runtime and regressions of application code. It is open source, so teams can self-host and extend it. Vendor: Criterion.rs contributors. Deployment model: self-hosted. Free; MIT or Apache License 2.0. Confirm details against the official site and a short proof-of-concept in your environment.
How does Criterion.rs differ from BenchmarkDotNet?
Compared with BenchmarkDotNet, scripting centers on Rust rather than C#, F#, Visual Basic. Criterion.rs lists protocols not recorded; BenchmarkDotNet lists not recorded. Status is active versus active. Use the Test Rig to compare full specs side by side before a proof-of-concept.
What scripting language and concurrency model does Criterion.rs use?
Criterion.rs uses Rust for scripting or scenario definition. Runtime model: code-first scenarios where virtual users execute scripted behavior under load. OS support: Windows, macOS, Linux. Protocols: not recorded. Match these to how your team already authors tests and which systems you must drive under load.
What is the cloud or enterprise path for Criterion.rs?
Criterion.rs is a focused benchmark harness rather than a browser or enterprise load controller. Use its measured workload and reporting model to isolate database or code performance before broader system testing. As open source, commercial support or hosted siblings may exist separately. Check the official site. Pricing note: Free; MIT or Apache License 2.0.
What are known limitations of Criterion.rs?
Criterion.rs limitations to weigh: self-hosted tools require you to provision, scale, and observe load generators yourself; protocol coverage is not fully recorded in this catalog entry. Status: active. Always validate against your target protocols and scale with a proof-of-concept. Confirm details against the official site and a short proof-of-concept in your environment.
