Summary Sponsored by Goldman Sachs. Java 8 has Streams, Scala has parallel collections, and GS Collections has ParallelIterables. Since we use parallelism to achieve better performance, it's interesting to ask: how well do they perform? We'll look at how these three APIs work with a critical eye toward performance. We'll also look at common performance pitfalls.

Bio Craig Motlin is the technical lead for GS Collections, a full-featured open-source Collections library for Java, and is the author of the framework's parallel, lazy API. He has worked at Goldman Sachs for 9 years on several teams focusing on application development before moving to the JVM Architecture team to focus on framework development.
