Practical profiling strategies

The benefits of profiling our Java applications to help identify and resolve performance issues have been established. We will next explore effective profiling strategies so that you can optimize your Java applications efficiently. This section covers strategies to identify performance bottlenecks and differentiate profiling approaches between development and production environments. We will also look at how to implement continuous profiling for long-term performance management.

Identifying performance bottlenecks

The primary goal of profiling is to identify performance bottlenecks. We can adopt several strategies to achieve this goal, including the following:

• Begin by monitoring CPU usage, memory consumption, and response times. These high-level metrics can help you identify areas that require deeper analysis.
• Consider using sampling profilers that can quickly identify methods that consume the most CPU time. Tools such as JVisualVM...
