Java Tip: When to use ForkJoinPool vs ExecutorService
Know your options for multithreaded programming on the Java platform The Fork/Join library introduced in Java 7 extends the existing Java concurrency package with support for hardware parallelism, a key feature of multicore systems. In this Java Tip Madalin Ilie demonstrates the performance impact of replacing the Java 6 ExecutorService class with Java 7’s ForkJoinPool in a web crawler application

Running JUnit tests in parallel with Maven | Java.net
A little-known but very useful feature slipped into JUnit 4 and recent versions of the Maven Surefire Plugin: support for parallel testing. This feature has been around for a while in TestNG, but has been missing in JUnit. And now, if you are a JUnit user, you too can run your tests in parallel! Running your tests in parallel is a powerful way to speed up your tests. Good automated tests should be

What is Kilim? Kilim is a message-passing framework for Java that provides ultra-lightweight threads and facilities for fast, safe, zero-copy messaging between these threads. It consists of a bytecode postprocessor (a "weaver"), a run time library with buffered mailboxes (multi-producer, single consumer queues) and a user-level scheduler and a type system that puts certain constraints on pointer a
Jacob Hookom's Blog: Accelerating Applications with Java 5 Concurrency
Posted by jhook on December 22, 2008 at 11:34 PM | Comments (2) After spending way too much time on ways to speed up web applications, you'll find that your greatest mileage comes in database optimizations, networking, and reducing the bytes downloaded (an example). Time spent optimizing Java code is seemingly insignificant between waiting on the request, waiting on the database, waiting on the se
