NSpeed
A client and server high performance network bandwidth measurement tool using Internet standards (HTTP/1, HTTP/2, HTTP/3*, WebRTC*, WebTransport*) Interoperable with standard web clients (like curl) and standard web servers (NGinx, Apache, etc)
Usage
nspeed [global options] [command] ... [command]
available commands:
- get
- put
- server
- ciphers
- api
The ciphers command can not be combined with others and can only be called once.
Each "command" has its own arguments, use -h to see them.
Overview of commands:
nspeed get [options] url
nspeed put [options] url size
nspeed server [options]
nspeed ciphers [options] target
nspeed api [options]
Examples
# download a single target four times at the same time
nspeed get -n 4 https://bouygues.testdebit.info/10G/10G.iso
# download 2 different targets
nspeed get https://bouygues.testdebit.info/10G/10G.iso get https://scaleway.testdebit.info/10G/10G.iso
# downlaod the same target in IPv4 and IPv6 at the same time
nspeed get -4 https://bouygues.testdebit.info/100M/100M.iso get -6 https://bouygues.testdebit.info/100M/100M.iso
# upload two 1GB to a single target (use "1g" for 1GB (1000*1000*1000 bytes) and "1G" for 1GiB (1024*1024*1024 bytes)
# accepted units: k,m,g,t,p,e and K,M,G,T,P,E
nspeed put -n 2 https://bouygues.testdebit.info/ 1g
# download & upload at the same time
nspeed put https://bouygues.testdebit.info/ 1g get https://bouygues.testdebit.info/1G/1G.iso
# start a server with default settings (host: 127.0.0.1, port: 7333, max time 10s , max size 1.1 TB)
nspeed server
# start a server at port 8888 with max time of 5 seconds and 1 GB max size accepted
nspeed server -p 8080 -t 5 -s 1g
# start a server listening on all interfaces but in IPv6 only
nspeed server -6 -a=""
# start a server listening on a specific IPv4 address
nspeed server -a 192.168.1.3
# start two instances of server, one listening on a specific IPv6 address and one on a specific IPv4 address
nspeed server -a 2001:1234:5678::3 server -a 192.168.1.3
# download 1GB from a nspeed server (the server generate content based on the url path: format is "/size[.ext][?ct=content-type]")
nspeed get http://localhost:7333/1g
# download 20 x 100MiB from a nspeed server
nspeed get -n 20 http://localhost:7333/100M
# with curl, download 1GiB from a nspeed local server
curl -o /dev/null http://localhost:7333/1G
# with curl, upload a local file "/path/to/file" to a nspeed server (with progress and result speed)
curl -T /path/to/file http://localhost:7333/ | tee
# same as above but without sending the filename to the server
curl -X POST --data-binary /path/to/file http://localhost:7333/ | tee
# download 1 GB from the local server and stop it
# how it works:
# - we launch a localhost server that will respond to one request then shutdown (-n 1)
# - we launch a get command
nspeed server -n 1 get -w 1 http://localhost:7333/1g
# with curl, download 1k bytes as content-type "text/plain" but with extention "jpg" from a nspeed server
curl -o /dev/null http://localhost:7333/1k.jpg?ct=text/plain
Installation
Binary distribution available here: dl.nspeed.app or in the release section
Download the one for your system and eventually rename it to nspeed.
On Unix systems make the file executable with: chmod +x nspeed
Source code with be released with v1.0
What's next?
- web UI (local & remote) - partitally implemented
- remote agent
- P2P (WebRTC)
- QUIC & HTTP/3 (waiting on Go code)
- formatted metrics (might be OpenMetrics ?)
- network & hardware information (routes, pci bandwidth, NIC info, erros, etc)
- gateway/router info & crosstalk information if available
