tommygun

HTTP Benchmarking Tool written in Node.JS.

Installation

NPM

npm install -g tommygun

Git

git clone git://github.com/brettlangdon/tommygun.git
cd ./tommygun
npm install -g

Configuration

Tommygun uses ini files to specify what urls and settings to test. Each section corresponds to the url to test and each property corresponds to specific settings for that given url.

The options available for each url are the same as those available to http.request (http://nodejs.org/api/http.html#http_http_request_options_callback).

When using the configuration setting headers you must provide the value as a valid JSON string.

Example

[localhost]
port = 8000
num = 5
 
[localhost/submit]
port = 8000
data = this is a test
headers = {"some": "values"}
method = post
num = 2
