_ JAVA PROFILING

Learn Java Profiling|

Understand your Java application's runtime behavior.

Java applications can be fast. Really fast, but they can also suffer with performance issues of all sorts – high CPU, memory leaks, thread contention, etc – all difficult to diagnose through debugging alone.

In this course, we’ll explore the fundamentals of Java profiling, using tools like JProfiler. We’ll investigate slow methods, memory leaks, excessive object allocation, and database performance issues using a sample Java application intentionally engineered with several performance defects.

All with the goal of making targeted optimizations based on real data.
