This is a simple and efficient web server to either send or retrieve arbitrary amounts of data. Useful for testing in cases where something like iperf is unfeasible or insufficient (eg proxy servers).

go get https://github.com/acobaugh/httpbwtest

./httpbwtest

or

docker run -p 8080:8080 quay.io/acobaugh/httpbwtest

Optionally, the PORT environment variable can be specified to change the port the server listens on. Default is 8080.

Sends size bytes of data.

Pattern is one of:

• random
• lohi (0xaf)
• hilo (0xaa)
• lohi (0x55)
• fs (0xff)
• zeros (0x00) - this is the default if / or any other value is requested

size is a human-readable size. If unspecified, defaults to 1B.

Accepts Content-Type: multipart/form-data. Immediately discards any file data sent on the form field named data.

Request 1GB of zeros.

% curl "localhost:8080/?size=1G" -o /dev/null
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed

Post 1GB of empty data.

% dd if=/dev/zero bs=1M count=1000 | curl -s -XPOST localhost:8080 -F data=@- -w"\nsize = %{size_upload}B\nspeed = %{speed_upload}B/s"
