Performance Enhancements

Many enhancements have been made to improve the performance of the Java 2 SDK in version 1.3.0 These changes include the addition of the Java HotSpot^TM Client Virtual Machine (VM) and the Java HotSpot Server VM, both of which implement high-performance Java HotSpot technology. The Java HotSpot Client VM is tuned to maximize performance on client systems, improving performance in areas of startup time and memory footprint. The Java HotSpot Server VM is tuned to maximize performance of program execution speed and is aimed at server applications that are less concerned with startup and memory footprint.

J2SE 1.3.0 also includes newly tuned class libraries for improved runtime performance.
