[VDBUH22] Laurentiu Spilca - Five most useful profiling techniques to use with modern Java apps

Contrary to popular opinion, profiling techniques aren’t only for identifying thread-related issues. In this presentation, you’ll learn five most useful profiling techniques that you’ll find tremendously helpful with modern Java apps: - Investigating SQL queries to identify faultily communication between the app and the DBMS - Finding hot spots in execution to optimize an app’s execution - Finding a call graph for learning new code - Profile reactive applications - Analyzing an app’s memory usage Such techniques with a profiling tool are a must for any Java developer regardless of the Java version or framework they use. Adding these techniques that we’ll demonstrate with examples to the definition of done in your development process, you’ll minimize the time spent on finding problems and deliver better and more optimal apps.
