// This test file provides performance benchmarks using gmeasure.

// It measures:
|
|
// - Read performance with various data sizes (small, medium, large)
|
|
// - ReadBytes performance across different scenarios
|
|
// - WriteTo performance for data copying
|
|
// - Constructor overhead with different buffer configurations
|
|
// - UnRead operation performance
|
|
// - Memory allocation patterns
|
|
// - Real-world scenarios (CSV parsing, log processing, variable streams)
|
|
//
|
|
// Benchmarks use gmeasure.Experiment for statistical analysis including:
|
|
// - Minimum, median, mean, max, and standard deviation
|
|
// - Multiple sample iterations for reliability
|
|
// - Performance reports integrated with test output
|
|
//
|
|
// Run with: go test -v to see performance reports.
