For Java programmers, iterating over a collection is the time-honored way of processing data. Now, from Java 8 onward, we will instead be writing stream programs—more concise, more expressive, and more maintainable. But how fast will they be? To understand the factors that govern stream performance, we need to look at the implementation of their different parts: beginning in a Spliterator, ending in a collector, and—for parallel streams—processing in the fork/join framework. This presentation uses measurements of these different stages to analyze the performance of some practical programs. The result will be guidelines for getting the best performance from Java 8 streams and for predicting when it is worthwhile to go parallel.

Kirk has been working in high performance and distributed computing for nearly 20 years. His focus has primarily been on performance, working on architecting, developing, and tuning applications running on Cray and other high performance computing platforms. Kirk now specializes in Java™, where he works in all aspects of performance and tuning in each phase of a project life cycle. Author, speaker, consultant, Kirk was recognized as a 2006 Java Champion recipient for his contributions to the Java community.

Przepraszamy za tak późną informację o spotkaniu.
