Chapter 14. Performance
When writing any program, the first challenge is to get it to compile and run correctly. The next challenge is often to get the program to run fast. Java virtual machine programs can be made faster in a number of ways.
Fast Virtual Machines
The best way to speed up a sluggish JVM program is to get a faster JVM implementation. This gives you a performance boost without risking the correctness of your program.
JVMs are available from a variety of sources and run on many different kinds of computers. Even on the same computer, the performance of one JVM implementation can be 20 times faster than that of another. Performance differences between JVM implementations stem from a variety of sources.
The most important performance improvement ...
