Advanced Topic 43 of 50 Software Engineering

Performance Profiling

Measuring where programs spend time and memory.

How it works

Profilers sample or instrument programs to show where time and memory go (CPU flame graphs, allocation profiles). Measure first, then optimize hot spots.

Where it is used

Finding bottlenecks.

Common pitfall

Optimizing without measurements wastes effort.

Where it fits in the course

Performance Profiling is topic 43 of 50 in Software Engineering, rated Advanced. It follows Cyclomatic Complexity. The next topic is Formal Verification.
