Performance Testing Of Web App

Performance Testing for Web App:

Page Load Time:

• Verify that all pages load within an acceptable time frame (e.g., under 3 seconds).
• Optimize server response time to minimize delays.
• Minimize the number of HTTP requests by optimizing assets (images, scripts, stylesheets).
• Evaluate and improve the order of loading critical resources (e.g., prioritize above-the-fold content).
• Implement lazy loading for images and content below the fold.

Resource Optimization:

• Compress and optimize images and files to reduce their size.
• Implement browser caching with appropriate cache control headers.
• Minify JavaScript and CSS files to reduce download size.
• Use asynchronous loading for non-essential scripts.
• Employ a Content Delivery Network (CDN) for assets to distribute load geographically.

Scalability and Load Handling:

• Conduct load testing to determine the website's capacity under different levels of traffic.
• Implement auto-scaling mechanisms to handle traffic spikes.
• Optimize database queries and indexes for improved query performance.
• Load test with simulated real-world user scenarios to assess performance.
• Monitor server response times and performance metrics during load tests.

Error Handling:

• Test how the website handles errors and failures under load.
• Implement graceful degradation for features that may fail under heavy load.
• Use proper HTTP status codes and error messages in responses.
• Monitor and log errors during load tests for analysis.
• Define a strategy for notifying administrators about critical errors.

Performance Monitoring:

• Set up performance monitoring tools to track key metrics over time.
• Monitor server health, response times, and resource utilization.
• Establish baseline performance metrics for comparison during load tests.
• Implement automated alerts for abnormal performance patterns.
• Continuously analyze monitoring data to identify opportunities for optimization.
