README

PHPBench is a benchmark runner for PHP analogous to PHPUnit but for performance rather than correctness.

Features include:

Revolutions: Repeat your code many times to determine average execution time.
Iterations: Sample your revolutions many times and review aggregated statistical data.
Process Isolation: Each iteration is executed in a separate process.
Reporting: Customizable reports and various output formats (e.g. console, CSV, Markdown, HTML).
Report storage and comparison: Store benchmarks locally to be used as a baseline reference, or to reference them later.
Memory Usage: Keep an eye on the amount of memory used by benchmarking subjects.
Assertions: Assert that code is performing within acceptable limits, or that it has not regressed from a previously recorded baseline.

See the documentation to find out more.
