This Node.js Cluster project is designed to demonstrate the use of the cluster module to create a multiprocessor Node.js application for better utilization of CPU cores. The project includes a simple Express application in app.js and a clustering logic in cluster.js.

Before running the application, ensure you have the following installed:

• Node.js (version 14.0.0 or higher)
• npm (Node Package Manager)

• app.js: Contains the main Express application logic.
• cluster.js: Manages the creation of multiple worker processes using the cluster module.
• package.json: Project configuration file with dependencies and start script.

1. Clone the repository:

   git clone https://github.com/saeedNW/node.js-cluster.git

2. Navigate to the project directory:

   cd node.js-cluster

3. Install dependencies:

   npm install

4. Start the application:

   npm start

   This will launch the application and utilize multiple CPU cores via the cluster module.

To test the application's performance, you can use the loadtest module. Follow these steps:

1. Install loadtest globally:

   npm install -g loadtest

2. Run the load test:

   loadtest -c 10 -t 10 -n 100 http://localhost:3000/cluster

   This command will simulate 10 clients (-c) making requests for 10 seconds (-t) with a total of 100 requests (-n) to the specified endpoint. Adjust the parameters as needed for your testing requirements.
