speedtest-go

speedtest-go

You can speedtest 2x faster than speedtest.net with almost the same result. See the experimental results..

This fork allows abstracts the implementation of the speed test to a package so it can be used by other go programs.

Inspired by sivel/speedtest-cli

API Installation

go get github.com/cbergoon/speedtest-go

API Usage

The code below finds closest available speedtest server and tests the latency, download, and upload speeds.

package main

import (
	"fmt"
	"github.com/cbergoon/speedtest-go/speedtest"
)

func main() {
	user, _ := speedtest.FetchUserInfo()

	serverList, _ := speedtest.FetchServerList(user)
	targets, _ := serverList.FindServer([]int{})

	for _, s := range targets {
		s.PingTest()
		s.DownloadTest()
		s.UploadTest()

		fmt.Printf("Latency: %s, Download: %f, Upload: %f\n", s.Latency, s.DLSpeed, s.ULSpeed)
	}
}

CLI Installation

OS X (homebrew)

$ brew tap showwin/speedtest

Summary of Experimental Results

Speedtest-go is a great tool because of following 2 reasons:

• Testing time is the SHORTEST compare to speedtest.net and sivel/speedtest-cli, especially about 2x faster then speedtest.net.
• Result is MORE CLOSE to speedtest.net than speedtest-cli.

Following data is summarized. If you got interested in, please see more details.

distance = distance to testing server

• 0 - 1000(km) ≒ domestic
• 1000 - 8000(km) ≒ same region
• 8000 - 20000(km) ≒ really far!
• 20000km is the half of the circumference of our planet.
