To improve the performance of a Node.js application that involves IO, you need to understand how your CPU cycles are spent and what is preventing higher degrees of parallelism in your application. In this article, Jorge Bay shares his insights on areas that cause throughput degradation and tips for how to boost performance.
If you've ever wondered what happens when your bytecode executes, join former Oracle G1GC performance-lead Monica Beckwith in her guided tour of just-in-time (JIT) compilation and runtime optimizations in OpenJDK HotSpot VM.
Throwing checked exceptions without declaration, changing final fields; these kinds of antics would never be tolerated by the Java language. But using Java bytecode these can be done readily. Few developers ever work with Java bytecode directly, but bytecode format is not difficult to understand. In this article Rafael Winterhalter takes us on a tour of Java bytecode & some of its capabilities
The existing Java Memory Model covers a lot in terms of Java language semantic guarantees. In this article we will delve into some of those semantics, and review the motivation for updating the JMM 3
