上一次讨论类似问题，还是在月初。刚好有老外网友做了一个实验，对 62 门编程语言速度做了一个比较，通过莱布尼茨公式计算 π 值，然后给出运行速度的排名，最慢是 Python （CPython）。实验过程和结果都公开透明，参见网址：https://github.com/niklas-heer/speed-comparison。 有时候，我挺理解那些对 Java 有偏见的程序员的。比如，Python ...

在 JDK 21 中，JEP 439（分代 ZGC）从 Targeted 状态提升到 Completed 状态。该 JEP 建议，扩展 Z Garbage Collector（ZGC），为年轻对象和老对象维护单独的代，从而提高应用程序的性能。这将使得 ZGC 可以更频繁地收集趋于早亡的年轻对象。 Z Garbage Collector 专为低延迟和高可 ...

在编程语言的争论中，Java常常被贴上“慢”的标签，尤其是与Python、C等语言相比。然而，最近的一项研究显示，Java的真实表现可能远超我们的想象，尤其是当它与现代技术结合时。特别是Spring框架的使用，往往被视为Java性能的绊脚石。今天，我们就来探讨这个问题，揭开Java性能的真相。 首先，许多程序员对Java的偏见源于过去的经验。早期版本的Java确实存在性能问题，尤其是在JDK1.4 ...

甲骨文 发布了Java 编程语言和虚拟机的 23 版本。作为 JDK 21 之后的第一个非 LTS 版本，最终的 12 个 JEP 特性包括： JEP 455：模式、instanceof 和 switch 中的原始类型（Primitive Types in Patterns, instanceof, and switch，预览） JEP 466：类文件 API（Class-File ...

Java 21 has arrived, and with it the latest implementation of Oracle's Java Development Kit (JDK). Oracle JDK 21 is a long-term support release (LTS) focused on serious performance improvements, ...

An Oracle-developed, low-latency Java garbage collector geared to large heaps could move to the open source community, if a proposal to do so gets community approval. Votes are due by November 8.

Generational Z Garbage Collector would lower garbage collection CPU overhead, lower heap memory overhead, and reduce the risk of allocations stalls, OpenJDK proposal says. A proposal floating in the ...
