Although Java is cross-platform, its performance and quality are greatly influenced by the features of the underlying native platform. Since the Java language and environment includes concurrency and multithreading (MT) as integral components, the native operating system's multithreading model and environment will greatly influence Java applications' quality and performance on that system. Sun's Java Virtual Machine (JVM), central to the performance and scalability of the Java Development Kit (JDK) for Solaris, is designed to take full advantage of multi-processor computing systems by using the native multithreading capabilities of Solaris. It performs bytecode interpretation using native multithreading and fast synchronization and, later this summer, will feature an improved memory system. These features provide developers with significant performance boosts requi... (more)
