java - 标记-清除算法JAVA

Question

标记-清除算法有“stop the world”的缺点，这意味着什么？世界指的是什么？为什么它会让世界停止运转？

Answer 1

关于这个算法的简单谷歌搜索带来了 this作为第一个网站(至少对我来说)

The main disadvantage of the mark-and-sweep approach is the fact that that normal program execution is suspended while the garbage collection algorithm runs. In particular, this can be a problem in a program that interacts with a human user or that must satisfy real-time execution constraints. For example, an interactive application that uses mark-and-sweep garbage collection becomes unresponsive periodically.

所以基本上你的程序只会在内存释放期间卡住。
