Description
speedtest is an application that measures the latency, jitter, packet loss, download bandwidth, and upload bandwidth of the network connection between the client and a nearby Speedtest Server.

Options

•   -h, --help
    Print usage information

•   -v Logging verbosity, specify multiple times for higher verbosity (e.g. -vvv)

•   -V, --version Print version number

•   -L, --servers List nearest servers

•   --selection-details Show server selection details

•   -s id, --server-id=id
    Specify a server from the server list using its id

•   -o hostname, --host=hostname
    Specify a server from the server list using its hostname

•   -f format_type --format=format_type
    Output format (default = human-readable) Note: Machine readable formats (csv, tsv, json, jsonl, json-pretty) use bytes as the unit of measure with max precision.

    format_type values are as follows:

•   -uunit_of_measure, --unitunit_of_measure Output unit for displaying speeds (Note: this is only applicable for ‘human-readable’ output format and the default unit is Mbps)

•   bps bits per second (decimal prefix)

•   kbps kilobits per second (decimal prefix)

•   Mbps megabits per second (decimal prefix)

•   Gbps gigabits per second (decimal prefix)

•   kibps kilobits per second (binary prefix)

•   Mibps megabits per second (binary prefix)

•   Gibps gigabits per second (binary prefix)

•   B/s bytes per second

•   kB/s kilobytes per second

•   MB/s megabytes per second

•   GiB/s gigabytes per second

•   auto-binary-bytes automatic in binary bytes

•   auto-decimal-bytes automatic in decimal bytes

•   auto-binary-bytes automatic in binary bits

•   auto-binary-bytes automatic in decimal bits

•   -a
    Shortcut for [-u auto-decimal-bits]

•   -A
    Shortcut for [-u auto-decimal-bytes]

•   -b
    Shortcut for [-u auto-binary-bits]

•   -B
    Shortcut for [-u auto-binary-bytes]

•   -P decimal_places --precision=decimal_places
    Number of decimal_places to use (default = 2, valid = 0-8)

•   -p yes|no --progress=yes|no
    Enable or disable progress bar (default = yes when interactive)

•   -I interface --interface=interface Attempt to bind to the specified interface when connecting to servers

•   -i ip_address --ip=ip_address Attempt to bind to the specified IP address when connecting to servers

•   --ca-certificate=path Path to CA Certificate bundle, see note below.

Output
Upon successful execution, the application will exit with an exit code of 0. The result will include latency, jitter, download, upload, packet loss (where available), and a result URL.

Latency and jitter will be represented in milliseconds. Download and upload units will depend on the output format as well as if a unit was specified. The human-readable format defaults to Mbps and any machine-readable formats (csv, tsv, json, jsonl, json-pretty) use bytes as the unit of measure with max precision. Packet loss is represented as a percentage, or Not available when packet loss is unavailable in the executing network environment.

The bytes per second measurements can be transformed into the human-readable output format default unit of megabits (Mbps) by dividing the bytes per second value by 125,000. For example:

38404104 bytes per second = 38404104 / 125 = 307232.832 kilobits per second = 307232.832 / 1000 = 307.232832 megabits per second

The value 125 is derived from 1000 / 8 as follows:

1 byte = 8 bits 1 kilobit = 1000 bits

38404104 bytes per second = 38404104 * 8 bits per byte = 307232832 bits per second = 307232832 / 1000 bits per kilobit = 307232.832 kilobits per second

The Result URL is available to share your result, appending .png to the Result URL will create a shareable result image.

Example human-readable result:

    $ speedtest
        Speedtest by Ookla
         Server: Speedtest.net - New York, NY (id = 10390)
            ISP: Comcast Cable
        Latency:    57.81 ms   (3.65 ms jitter)
       Download:    76.82 Mbps (data used: 80.9 MB)
         Upload:    37.58 Mbps (data used: 65.3 MB)
    Packet Loss:     0.0%
     Result URL: https://www.speedtest.net/result/c/8ae1200c-e639-45e5-8b55-41421a079250

Network Timeout Values
By default, network requests set a timeout of 10 seconds. The only exception to this is latency testing, which sets a timeout of 15 seconds.

Fatal Errors
Upon fatal errors, the application will exit with a non-zero exit code.

Initialization Fatal Error Examples:

Configuration - Couldn't connect to server (Network is unreachable)

Configuration - Could not retrieve or read configuration (ConfigurationError)

Stage Execution Fatal Error Example:

[error] Error: [1] Latency test failed for HTTP

[error] Error: [36] Cannot open socket: Operation now in progress

[error] Failed to resolve host name. Cancelling test suite.

[error] Host resolve failed: Exec format error

[error] Cannot open socket: No route to host

[error] Server Selection - Failed to find a working test server. (NoServers)

SSL Certificate Locations
By default the following paths are checked for CA certificate bundles on linux machines:

    /etc/ssl/certs/ca-certificates.crt
    /etc/pki/tls/certs/ca-bundle.crt
    /usr/share/ssl/certs/ca-bundle.crt
    /usr/local/share/certs/ca-root-nss.crt
    /etc/ssl/cert.pem

If the device under test does not have one of the above mentioned files, then the canonical and up to date CA certificate bundle provided by the curl project can be manually downloaded into a specific location. This specific location can be provided as a parameter per the following example:

    wget https://curl.haxx.se/ca/cacert.pem
    ./ookla --ca-certificate=./cacert.pem
