Performance has been an important issue for
Java developers ever since the first version hit the
streets. Over the years, Java performance has improved
dramatically, but tuning is essential to get the best
results, especially for J2EE applications. You can never
have code that runs too fast.
Java Peformance
Tuning, 2nd edition provides a comprehensive and
indispensable guide to eliminating all types of
performance problems. Using many real-life examples to
work through the tuning process in detail, JPT shows how
tricks such as minimizing object creation and replacing
strings with arrays can really pay off in improving your
code's performance.
Tuning J2EE applications bears
many similarities to tuning J2SE apps, but important and
specific considerations apply. For this reason,
Java
Performance Tuning, Second Edition includes four new
chapters: a new chapter on J2EE application tuning in
general followed by chapters on tuning JDBC, servlets
and JSPs, and EJBs.
Java Performance Tuning
offers common-sense advice about what to tune and what
to leave alone, emphasizing techniques that provide big
performance gains with minimal code restructuring. It
gives you crucial guidance that helps you tune without
destroying your program's architecture. Blindly changing
things in an effort to make a program run faster is a
great way to create buggy, unmaintainable code.
Java
Performance Tuning teaches you to work efficiently
and effectively, resulting in code that is robust,
maintainable, and fast.
Java Performance
Tuning, Second Edition shows you how to:
- Create a performance plan
- Glean information about your program's behavior
from profiling tools
- Identify bottlenecks before tuning
- Minimize the number of objects your program
creates, particularly critical for J2EE applications
- Optimize the use of strings
- Avoid performance penalties from inefficient code
- Improve the behavior of loops and switches
- Optimize I/O behavior
- Use appropriate algorithms for sorting and other
common tasks
- Use threads effectively
- Optimize the performance of distributed systems
- Speed up servlets and JSPs
- Structure JDBC usage efficiently
- Use effective design patterns to optimize EJB
performance
