Node HTTP Performance Analysis Tool

Installation

git clone https://github.com/mrodrig/node-performance.git

Usage

cd ./node-performance/
npm install
cd ./lib/

• Options

  • Open ./options.json and make the necessary changes.
  • Currently, this HTTP performance testing script allows for the following options to be set:
    • URL - The web site address that you wish to test. Be sure to include an appropriate protocol (ie. http://, https://, etc)
    • HTTP_METHOD - The HTTP Method that will be used to make this call (ie. GET, POST, DELETE, etc)
    • REQ_BODY - This is a key: value JSON document that will allow you to pass data in the body of the requests.
    • REQ_HEADERS - This is a key: value JSON document that will allow you to pass data in the headers of the requests.
    • NUM_PASSES - The number of times that you wish to run the multiple requests. Each pass is run in series and will asynchronously make NUM_REQUESTS requests to the given web address.
    • NUM_REQUESTS - The number of HTTP requests to make asynchronously in each pass.

• Once the options have been configured, run:

node perfTest.js

Features

• Provides a baseline for a single request
• Allows you to see how your app/web service/endpoint scales with multiple requests asynchronously
• Provides summary information
• Passes applicable information back to init method's callback

TODO

• Convert to node module to allow for easier testing
• Pass more applicable data back to the user
