Java Virtual Threads: a Case Study

This article explores JDK 21's virtual threads, comparing their performance with Open Liberty's thread pool. It covers key findings like throughput, ramp-up times, and memory footprint. Despite advantages, virtual threads showed unexpected performance issues, especially in CPU-intensive workloads. This analysis guides Java developers on when and how to use virtual threads in their applications.

Spring Boot 3.2 and Spring Framework 6.1 Add Java 21, Virtual Threads, and CRaC

Spring Framework 6.1 and Spring Boot 3.2 run on Java 21. They make concurrent programming simpler and more efficient with virtual threads, as well as improving reactive programming and Kotlin coroutines. For “Scale to Zero” startup time reduction, the OpenJDK project CRaC received initial support, while the existing GraalVM Native Image integration got faster through a GraalVM release.

Designing for Concurrency: the Hilbert’s Hotel Problem in Go

In this article, we want to show how achieving concurrency is the result of an appropriate design. A concurrent solution may turn out to be more elegant and easier to reason about than an equivalent sequential algorithm. To illustrate these concepts we use, as an example, the Hilbert’s Hotel mathematical problem.

Virtual Threads: New Foundations for High-Scale Java Applications

Virtual threads are a lightweight implementation of Java threads, delivered as a preview feature in Java 19. They dramatically reduce the effort of writing, maintaining, and observing high-throughput concurrent applications. Virtual threads breathe new life into the familiar thread-per-request style of programming, allowing it to scale with near-optimal hardware utilization.

Boosting WebAssembly Performance with SIMD and Multi-Threading

Early implementations of WebAssembly's SIMD and multi-threading proposals show that WebAssembly is narrowing the gap with native performance, by using SIMD instructions and multicore CPUs. Significant performance improvements have been observed in compute-intensive tasks (machine-learning, bio-informatics, scientific computing).

FPGAs Supercharge Computational Performance

Originally used in the development of new hardware, new, cloud-based FPGAs are making the technology more accessible. The dramatic improvements in speed and lower costs over traditional CPUs means more companies can start benefiting from the technology. FPGAs are fundamentally concurrent, which makes them an ideal tool for data-intensive, parallel processing problems.

Microservice Threading Models and their Tradeoffs

A microservice's efficiency and resource consumption patterns are dramatically affected by its threading model. Choosing the correct model for your solution is a basic requirement for success. Glenn Engstrand investigates multiple options for a service's execution life-cycle, gives examples of the benefits and drawbacks for each choice, and provides recommendations for each model's implementation.
