What does "profiling" mean in programming?
profiling is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
Measuring the runtime performance of code to identify where time and memory are being spent. Profiling pinpoints bottlenecks so you know exactly what to optimize instead of guessing.
