# speedtest-go
**Full-featured Command Line Interface and pure [Go API](#go-api) to Test Internet Speed using [speedtest.net](http://www.speedtest.net/)**.
You can speedtest 2x faster than [speedtest.net](http://www.speedtest.net/) with almost the same result. [See the experimental results](https://github.com/showwin/speedtest-go#summary-of-experimental-results).
Inspired by [sivel/speedtest-cli](https://github.com/sivel/speedtest-cli)
## CLI
### Installation
#### macOS (homebrew)
```bash
$ brew tap showwin/speedtest
$ brew install speedtest
### How to Update ###
$ brew update
$ brew upgrade speedtest
```
#### [Nix](https://nixos.org) (package manager)
```bash
# Enter the latest speedtest-go environment
$ nix-shell -p speedtest-go
```
#### Other Platforms (Linux, Windows, etc.)
Please download the compatible package from [Releases](https://github.com/showwin/speedtest-go/releases).
If there are no compatible packages you want, please let me know on [Issue Tracker](https://github.com/showwin/speedtest-go/issues).
### Usage
```bash
$ speedtest --help
usage: speedtest-go []
Flags:
--help Show context-sensitive help (also try --help-long and --help-man).
-l, --list Show available speedtest.net servers.
-s, --server=SERVER ... Select server id to speedtest.
--custom-url=CUSTOM-URL Specify the url of the server instead of fetching from speedtest.net.
--saving-mode Test with few resources, though low accuracy (especially > 30Mbps).
--json Output results in json format.
--unix Output results in unix like format.
--location=LOCATION Change the location with a precise coordinate (format: lat,lon).
--city=CITY Change the location with a predefined city label.
--city-list List all predefined city labels.
--proxy=PROXY Set a proxy(http[s] or socks) for the speedtest.
eg: --proxy=socks://10.20.0.101:7890
eg: --proxy=http://10.20.0.101:7890
--source=SOURCE Bind a source interface for the speedtest.
--dns-bind-source DNS request binding source (experimental).
eg: --source=10.20.0.101
-m --multi Enable multi-server mode.
-t --thread=THREAD Set the number of concurrent connections.
--search=SEARCH Fuzzy search servers by a keyword.
--ua Set the user-agent header for the speedtest.
--no-download Disable download test.
--no-upload Disable upload test.
--ping-mode Select a method for Ping (support icmp/tcp/http).
-u --unit Set human-readable and auto-scaled rate units for output
(options: decimal-bits/decimal-bytes/binary-bits/binary-bytes).
-d --debug Enable debug mode.
--version Show application version.
```
#### Test Internet Speed
Simply use `speedtest` command. The closest server is selected by default. Use the `-m` flag to enable multi-measurement mode (recommended)
```bash
## unix like format output
# speedtest --unix
$ speedtest

```
#### Test with a virtual location
With `--city` or `--location` option, the closest servers of the location will be picked.
You can measure the speed between your location and the target location.
```bash
$ speedtest --city-list
Available city labels (case insensitive):
CC CityLabel Location
(za) capetown [-33.9391993, 18.4316716]
(pl) warsaw [52.2396659, 21.0129345]
(sg) yishun [1.4230218, 103.8404728]
...
$ speedtest --city=capetown
$ speedtest --location=60,-110
```
#### Memory Saving Mode
With `--saving-mode` option, it can be executed even in an insufficient memory environment like IoT devices.
The memory usage can be reduced to 1/10, about 10MB of memory is used.
However, please be careful that the accuracy is particularly low, especially in an environment of 30 Mbps or higher.
To get more accurate results, run multiple times and average.
For more details, please see [saving mode experimental result](https://github.com/showwin/speedtest-go/blob/master/docs/saving_mode_experimental_result.md).
⚠️This feature has been deprecated > v1.4.0, because speedtest-go can always run with less than 10MBytes of memory now. Even so, `--saving-mode` is still a good way to reduce computation.
## Go API
```bash
go get github.com/showwin/speedtest-go
```
### API Usage
The [code](https://github.com/showwin/speedtest-go/blob/master/example/naive/main.go) below finds the closest available speedtest server and tests the latency, download, and upload speeds.
```go
package main
import (
"fmt"
"github.com/showwin/speedtest-go/speedtest"
)
func main() {
var speedtestClient = speedtest.New()
// Use a proxy for the speedtest. eg: socks://127.0.0.1:7890
// speedtest.WithUserConfig(&speedtest.UserConfig{Proxy: "socks://127.0.0.1:7890"})(speedtestClient)
// Select a network card as the data interface.
// speedtest.WithUserConfig(&speedtest.UserConfig{Source: "192.168.1.101"})(speedtestClient)
// Get user's network information
// user, _ := speedtestClient.FetchUserInfo()
// Get a list of servers near a specified location
// user.SetLocationByCity("Tokyo")
// user.SetLocation("Osaka", 34.6952, 135.5006)
// Search server using serverID.
// eg: fetch server with ID 28910.
// speedtest.ErrServerNotFound will be returned if the server cannot be found.
// server, err := speedtest.FetchServerByID("28910")
serverList, _ := speedtestClient.FetchServers()
targets, _ := serverList.FindServer([]int{})
for _, s := range targets {
// Please make sure your host can access this test server,
// otherwise you will get an error.
// It is recommended to replace a server at this time
s.PingTest(nil)
s.DownloadTest()
s.UploadTest()
// Note: The unit of s.DLSpeed, s.ULSpeed is bytes per second, this is a float64.
fmt.Printf("Latency: %s, Download: %s, Upload: %s\n", s.Latency, s.DLSpeed, s.ULSpeed)
s.Context.Reset() // reset counter
}
}
```
The [code](https://github.com/showwin/speedtest-go/blob/master/example/packet_loss/main.go) will find the closest available speedtest server and analyze packet loss.
```go
package main
import (
"fmt"
"github.com/showwin/speedtest-go/speedtest"
"github.com/showwin/speedtest-go/speedtest/transport"
"log"
)
func checkError(err error) {
if err != nil {
log.Fatal(err)
}
}
// Note: The current packet loss analyzer does not support udp over http.
// This means we cannot get packet loss through a proxy.
func main() {
// Retrieve available servers
var speedtestClient = speedtest.New()
serverList, _ := speedtestClient.FetchServers()
targets, _ := serverList.FindServer([]int{})
// Create a packet loss analyzer, use default options
analyzer := speedtest.NewPacketLossAnalyzer(nil)
// Perform packet loss analysis on all available servers
for _, server := range targets {
err := analyzer.Run(server.Host, func(packetLoss *transport.PLoss) {
fmt.Println(packetLoss, server.Host, server.Name)
// fmt.Println(packetLoss.Loss())
})
checkError(err)
}
// or test all at the same time.
packetLoss, err := analyzer.RunMulti(targets.Hosts())
checkError(err)
fmt.Println(packetLoss)
}
```
## Summary of Experimental Results
Speedtest-go is a great tool because of the following five reasons:
* Cross-platform available.
* Low memory environment.
* We are the first **FULL-FEATURED** open source speed testing project based on speedtest.net, including down/up rates, jitter and packet loss, etc.
* Testing time is the **SHORTEST** compare to [speedtest.net](http://www.speedtest.net/) and [sivel/speedtest-cli](https://github.com/sivel/speedtest-cli), especially about 2x faster than [speedtest.net](http://www.speedtest.net/).
* Result is **MORE CLOSE** to [speedtest.net](http://www.speedtest.net/) than [speedtest-cli](https://github.com/sivel/speedtest-cli).
The following data is summarized. If you got interested, please see [more details](https://github.com/showwin/speedtest-go/blob/master/docs/experimental_result.md).
### Download (Mbps)
distance = distance to testing server
* 0 - 1000(km) ≒ domestic
* 1000 - 8000(km) ≒ same region
* 8000 - 20000(km) ≒ really far!
* 20000km is half of the circumference of our planet.
