API Performance Analyzer & Load Testing Toolkit

This project demonstrates how to perform load testing on REST APIs using the Locust framework.

Overview

The API Performance Profiler simulates multiple concurrent users sending requests to an API endpoint and measures performance metrics such as response time, throughput, and failure rate.

Features

• Simulates concurrent users hitting an API
• Measures response time and latency
• Tracks request throughput (RPS)
• Displays results on an interactive dashboard

Technologies Used

• Python
• Locust
• REST API Testing

How to Run

1. Install dependencies

pip install locust

2. Run Locust

locust

3. Open browser

http://localhost:8089

4. Enter test parameters and start load testing.

Example Test

Tested endpoint: https://jsonplaceholder.typicode.com/posts

Users simulated: 10
Spawn rate: 2 users/sec

Output Metrics

• Requests per second
• Average response time
• Failure rate
• Performance statistics dashboard
