是多线程的node.js版本? [英] A version of node.js that is multi-threaded?
问题描述
node.js是单线程的并且遵循事件模型是很棒的，但是除此之外，它对我没有多大帮助.我有很多CPU绑定的任务，我希望每个服务器请求都在单独的线程中处理.有没有人创建过多线程的node.js分支?
It's great that node.js is single threaded and follows an event model, but besides that it doesn't help me much. I have alot of cpu-bound tasks and I want each server request to be handled in a separate thread. Has anyone created a node.js fork that is multi-threaded yet?
我的意思不是像 webworker-threads 这样的模块，我需要在其中包装我的每个功能(在大型项目中都很麻烦).我的意思是，每个请求都像大多数其他Web服务器一样作为单独的线程进入哪里?
I don't mean a module like webworker-threads where I need to wrap each one of my functions (which gets cumbersome for large projects). I mean, where each request comes in as a separate thread like most other web servers?
推荐答案
The common solution is to spawn several node.js threads (up to the number of CPU cores) using build-in cluster module or some third-party library.
在单独的线程中处理每个请求违背了node.js的理念，并使所有node.js的优势无效.使用node.js来完成这些任务毫无意义，因为还有很多其他Web服务器会做得更好.
Handling each request in a separate thread goes against node.js philosophy and nullifies all node.js advantages. There is no point in using node.js for such tasks, because there is a lot of other web servers which will do it much better.
另一方面，node.js为您提供了一种处理Web请求的更有效的方法.因此，node.js不会为每个请求生成一个新线程，而是使用100％的单个CPU内核来处理单个线程(或小的线程池)中的所有请求.
On the other side, node.js offers you a more efficient way of handling web requests. So, instead of spawning a new thread for each request, node.js handles all requests in a single thread (or in a small pool of threads) using 100% of a single CPU core.
您还应该记住，node.js是为处理I/O绑定任务而设计的，可以击败其中的任何其他Web服务器.但是node.js不太擅长处理CPU限制的任务(例如计算).因此，如果处理每个请求都需要进行大量计算，那么您选择了错误的工具.
You should also keep in mind that node.js was designed for handling I/O bound tasks and can beat any other web server in it. But node.js is not so good at handling CPU bound tasks (e.g. calculations). So, if handling each request requires a lot of calculations then you picked the wrong tool.
