Performance Testing & Profiling

Learn to use tools and methodologies for performance testing, profiling, and identifying bottlenecks in your applications.

What is Performance Testing?

Ever wonder if your app can handle thousands of users? That's where performance testing comes in!

It's about evaluating how a system behaves under a particular workload. We want to know if it's fast, stable, and responsive.

Why Performance Test?

Why bother with performance testing?

  • User Experience: Slow apps frustrate users and make them leave.
  • Reliability: Prevent crashes when traffic spikes.
  • Scalability: Understand how many users your system can support before needing more resources.
