Overview

Package throughput provides functionality for producing content at an extremely high rate.

Example

package main

import (
	"os"

	"github.com/stevenxie/dgen/throughput"
)

func main() {
	const repstr = "test string "
	throughput.Dump(repstr, 3, throughput.RecommendedBufSize, os.Stdout)
}

Output:

test string test string test string

Constants

const RecommendedBufSize = 1000

RecommendedBufSize is the buffer size recommended for Dump's bufsize argument.

It is roughly based on the speed of writing to os.Stdout. A different size should be considered for programs that do not write directly to the display.

Functions

func Dump

func Dump(s string, repeats, bufsize int, out io.Writer) (n int, err error)

Dump repeats s, and streams the result to out.

Dump's bufsize argument indicates the maximum string size (in bytes) for which a buffering strategy should be used to reduce the frequency of writes to out.

To disable buffering entirely, set bufsize to 0.
