bombardier

bombardier is a HTTP(S) benchmarking tool. It is written in Go programming language and uses excellent fasthttp instead of Go's default http library, because of its lightning fast performance.

With bombardier v1.1 and higher you can now use net/http client if you need to test HTTP/2.x services or want to use a more RFC-compliant HTTP client.

Tested on go1.8 and higher.

Installation

You can grab binaries in the releases section. Alternatively, to get latest and greatest run:

go get -u github.com/codesenberg/bombardier

Usage

bombardier [<flags>] <url>

For a more detailed information about flags consult GoDoc.

Known issues

AFAIK, it's impossible to pass Host header correctly with fasthttp, you can use net/http(--http1/--http2 flags) to workaround this issue.

Examples

Example of running bombardier against this server:

> bombardier -c 125 -n 10000000 http://localhost:8080
Bombarding http://localhost:8080 with 10000000 requests using 125 connections
 10000000 / 10000000 [============================================] 100.00% 37s Done!
Statistics        Avg      Stdev        Max
  Reqs/sec    264560.00   10733.06     268434
  Latency      471.00us   522.34us    51.00ms
  HTTP codes:

Or, against a realworld server(with latency distribution):

> bombardier -c 200 -d 10s -l http://ya.ru
Bombarding http://ya.ru for 10s using 200 connections
[=========================================================================] 10s Done!

Overview

Command line utility bombardier is a fast cross-platform HTTP benchmarking tool written in Go.

Installation:

go get -u github.com/codesenberg/bombardier

Usage:

bombardier [<flags>] <url>

Flags:

    --help                  Show context-sensitive help (also try --help-long
                            and --help-man).
    --version               Show application version.
-c, --connections=125       Maximum number of concurrent connections
-t, --timeout=2s            Socket/request timeout
-l, --latencies             Print latency statistics
-m, --method=GET            Request method
-b, --body=""               Request body
-f, --body-file=""          File to use as request body
-s, --stream                Specify whether to stream body using chunked
                            transfer encoding or to serve it from memory
    --cert=""               Path to the client's TLS Certificate
    --key=""                Path to the client's TLS Certificate Private Key
-k, --insecure              Controls whether a client verifies the server's
                            certificate chain and host name
-H, --header="K: V" ...     HTTP headers to use(can be repeated)
-n, --requests=[pos. int.]  Number of requests
-d, --duration=10s          Duration of test
-r, --rate=[pos. int.]      Rate limit in requests per second
    --fasthttp              Use fasthttp client
    --http1                 Use net/http client with forced HTTP/1.x
    --http2                 Use net/http client with enabled HTTP/2.0
-p, --print=<spec>          Specifies what to output. Comma-separated list of
                            values 'intro' (short: 'i'), 'progress' (short:
                            'p'), 'result' (short: 'r'). Examples:

                              * i,p,r (prints everything)
                              * intro,result (intro & result)
                              * r (result only)

-q, --no-print              Don't output anything
-o, --format=<spec>         Which format to use to output the result. <spec>

                            understood by bombardier or a path to the
                            user-defined template, which uses Go's
                            text/template syntax, prefixed with 'path:' string
                            (without single quotes), i.e.
                            "path:/some/path/to/your.template" or
                            "path:C:\some\path\to\your.template" in case of
                            Windows. Formats understood by bombardier are:

                              * plain-text (short: pt)
                              * json (short: j)

Args:

<url>  Target's URL
