Chapter 21. Performance Tuning of Java Applications
The goal of performance analysis in any Java-based application is to determine which parts of a program require optimization to increase their execution speed or lower their memory usage. Performance analysis is used for the following things:
- Pro-active bottleneck identification
- Application profiling
- Fixing scenarios that are not meeting requirements/SLAs
Based on performance analysis, bottlenecks can be identified and performance tuning can be carried out.
In this chapter, we will discuss the following topics:
- Performance bottlenecks in applications and key challenges posed by these
- Solutions for resolving bottlenecks, for example, object reuse, delayed initiation, and so on
- Performance tuning tools for Java applications, for example, Netprofiler
