SpeedTest.jl

Run network speed tests from Julia.

Overview

This package facilitates network performance tests (i.e. speed tests) using the Network Diagnostic Tool (NDT) and Measurement Lab servers.

Installation

This package requires web100clt, a part of the NDT client command line utility.

On macOS:

brew install web100clt

On linux:

apt update && apt install -y git automake gcc make libssl-dev libjansson-dev python
git clone --recursive https://github.com/ndt-project/ndt
cd ndt/I2util && ./bootstrap.sh && ./configure && make && make install
cd ndt && ./bootstrap && ./configure && make

Please note that I cannot help you troubleshoot issues with NDT utilities.

---

Then install this package as you would normally:

# SpeedTest.jl is not currently registered as an official package
# Please install the development version from GitHub:
Pkg.clone("git://GitHub.com/ellisvalentiner/SpeedTest.jl")

If you encounter a clear bug, please file a minimal reproducible example on GitHub.

Usage

using SpeedTest

nearest_server = get_ndt_servers(policy="nearest")
server_name = nearest_server["fqdn"]
raw = run_test(server_name)
print(raw)

# The slowest link in the end-to-end path is a 10 Mbps Ethernet or WiFi 11b subnet
# Information: Other network traffic is congesting the link
# Server 'ndt.iupui.mlab1.ord04.measurement-lab.org' is not behind a firewall. [Connection to the ephemeral port was successful]
# Client is probably behind a firewall. [Connection to the ephemeral port failed]
# Packet size is preserved End-to-End
# Server IP addresses are preserved End-to-End
# Information: Network Address Translation (NAT) box is modifying the Client's IP address
#   Server says [68.51.212.235] but Client says [ 10.0.1.5]

or more simply

using SpeedTest
