Performance is now the area where Java is being put to the test, offering ever greater competitive advantage for those who master it. In this book, one of the world's leading software optimization experts presents 48 lessons that address virtually every aspect of Java server-side performance, Java Performance and Scalability, Volume I proves that, through careful attention to underlying source code and program design, the Java programming language can meet and exceed developers' greatest expectations. Dov Bulka targets the most common and critical Java performance pitfalls, offering dozens of practical tips and solutions covering each performance-critical area. Bulka has done the hard work of digging deep into the JDK to understand Java performance in unprecedented depth. This book includes not only code examples, but actual measurements quantifying the improvements they deliver. Coverage includes strings, containers, numerics, I/O, RMI, JDBC, servlets, JSP, and much more -- including a complete case study that walks through improving the performance of a Web server by a full order of magnitude.

Dalla quarta di copertina:

This book was written with one goal in mind: to provide Java programmers with the expertise needed to build efficient, scalable Java code. The author shares his experience in server-side performance tuning through measured performance assessments, called optimizations. Each optimization discusses techniques to improve the performance and scalability of your code. Every claim is substantiated with hard numbers and an experience-based evaluation. Java™ Performance and Scalability, Volume 1, provides invaluable advice that you will, no doubt, find useful in your coding.

Presented in 48 concise lessons that target the most common and critical performance pitfalls, this book offers a plethora of practical tips and solutions for boosting the performance of your programs. These lessons cover performance-critical areas such as memory management, garbage collection, caching, and multithreading.

Specific lessons include:

  • Reserving StringBuffer capacity
  • Avoiding premature object creation
  • Creating an efficient vector class
  • Designing caching into your API
  • The cost of synchronization
  • Parallel subtasks
  • JNI efficiency
  • Varying the server workload and RMI network plumbing
  • Using ServletOutputStream
  • Caching JDBC™ connections

In addition to providing hard numbers that quantify the optimizations, the author concludes the book with an application demonstrating the effectiveness of the performance optimizations. The exercise takes a typical program and increases its performance fourfold through a series of steps that tie together the lessons learned throughout the book. He offers both the means and the proof to better coding.
