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 ...
