Parallel-lazy performance: Java 8 vs Scala vs GS Collections
Track: Solutions Track

Location:

Abstract:
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, the performance of Java 8 lambdas, and potential optimizations to the three libraries.
