# Criterion benchmarks

These are benchmarks using [Criterion](https://github.com/bheisler/criterion.rs), a microbenchmarking tool for Rust.

Run all benchmarks with `cargo bench`

Or run individual benchmarks like `cargo bench -- <regex>` e.g. `cargo bench -- parse`
Add Criterion benchmarks for parser (#7686) This PR sets up [Criterion](https://github.com/bheisler/criterion.rs) for benchmarking in the main `nu` crate, and adds some simple parser benchmarks. To run the benchmarks, just do `cargo bench` or `cargo bench -- <regex matching benchmark names>` in the repo root: ```bash 〉cargo bench -- parse ... Running benches/parser_benchmark.rs (target/release/deps/parser_benchmark-75d224bac82d5b0b) parse_default_env_file time: [221.17 µs 222.34 µs 223.61 µs] Found 8 outliers among 100 measurements (8.00%) 5 (5.00%) high mild 3 (3.00%) high severe parse_default_config_file time: [1.4935 ms 1.4993 ms 1.5059 ms] Found 11 outliers among 100 measurements (11.00%) 7 (7.00%) high mild 4 (4.00%) high severe ``` Existing benchmarks from `nu-plugin` have been moved into the main `nu` crate to keep all our benchmarks in one place. 2023-01-05 20:39:54 +01:00			`# Criterion benchmarks`
