为什么内存泄漏这么严重? [英] Why is memory leak so bad?

问题描述

我知道内存泄漏很糟糕，我应该总是释放动态分配的内存，而内存泄漏是不好的做法.我的问题是为什么内存泄漏在当今具有大 RAM 的现代操作系统中被认为如此糟糕.我的意思是小的内存泄漏(可能小于 1 MB)而不是一些消耗大量内存的真正大的结构.

I know memory leak is bad and I should always free dynamically allocated memory, and having memory leak is bad practice. My question is why memory leak considered so bad in todays modern operating system with large RAM. I mean to small memory leaks (maybe less than one MB) and not of some really big structures that consume a lot of memory.

推荐答案

内存泄漏很糟糕，因为您的程序会要求资源并在其整个生命周期内保持它们被占用，即使它不再需要它们.如果你在程序启动时有一个大小为 X 的静态泄漏并且它不会随着时间的推移而增长，那很不幸，但可能不是世界末日.如果每次执行 Y 时都有泄漏，那就是一个更大的问题，因为程序的内存消耗会继续增长，最终会占用不合理的资源量.

Memory leaks are bad because your program claims resources and keeps them occupied for its entire lifecycle, even though it does not need them anymore. If you have a static leak the size of X when the program starts and it does not grow over time it's unfortunate, but probably not the end of the world. If you have a leak every time you perform Y, it's a much bigger problem, as the program's memory consumption will continue growing and will eventually take up an unreasonable amount of resources.
