Speedtest
Simple down/upload bandwidth test in browser javascript.
It has a simple interface with only the essentials. There are no dependencies other than the binary files. It doesn't even require a backend language such as PHP and runs great on static hosting.
You simply upload the index.html file and generate
the binary testing files.
Example
The link below has the same HTML file (with stats)
and is basic static webhosting with no backend
processing. The test files were generated using the
fallocate command.
You can change the number precision up to 3 decimals using the arrow keys on your keyboard.
Installation
Just clone the repo:
git clone https://github.com/fvdm/speedtestOr download the index.html file:
wget https://raw.githubusercontent.com/fvdm/speedtest/master/index.htmlBinary files
To keep the repository small I have not included the test binaries.
You can instantly generate them yourself:
# on linux
fallocate -l 1m 1mb.bin
fallocate -l 5m 5mb.bin
fallocate -l 10m 10mb.bin
fallocate -l 100m 100mb.bin
fallocate -l 1000m 1000mb.bin
# on macOS
mkfile -n 1m 1mb.bin
mkfile -n 5m 5mb.bin
mkfile -n 10m 10mb.bin
mkfile -n 100m 100mb.bin
mkfile -n 1000m 1000mb.bin
# on Windows
# Open the Command Prompt as Administrator
fsutil file createnew 1mb.bin 1000000
fsutil file createnew 5mb.bin 5000000
fsutil file createnew 10mb.bin 10000000
fsutil file createnew 100mb.bin 100000000
fsutil file createnew 1000mb.bin 1000000000
# others like Synology
dd if=/dev/zero of=1mb.bin bs=1 count=0 seek=1M
dd if=/dev/zero of=5mb.bin bs=1 count=0 seek=5M
dd if=/dev/zero of=10mb.bin bs=1 count=0 seek=10M
dd if=/dev/zero of=100mb.bin bs=1 count=0 seek=100M
dd if=/dev/zero of=1000mb.bin bs=1 count=0 seek=1000MThese commands only create the files in the filesystem.
No bytes are actually written to the storage.
The suffix m is megabytes and g is gigabytes and so on.
Or you can download them from my server.
Please don't hotlink!!
Note on testing
With these kind of tools you are testing the available bandwidth of the slowest connection between your device and the host. When your web server connection is slower than your own network, you are actually testing the server's bandwidth instead of your own.
There can be many causes for slow connections, like the type of wiring, other devices, interference, packetloss or the peering between network providers somewhere along the route.
For example, I tested this speedtest from my own server to my home network both connected from Amsterdam and I got only 70 Mbit but using my provider's speedtest I get double at least. Doing the same to my LiquidSky box in Frankfurt I easily get over 900 Mbit. So there is a bottleneck somewhere between the web server and my home ISP.
The speedtest is at its best when the connection is as short as possible. For example, on your NAS or RPi to check on your LAN bandwidth.
