我多少个线程可以同时运行？ [英] How many threads can I run concurrently?

问题描述

一个注释我的另一个问题说，我只能运行这么多线程concurretnly，这是我在其他地方看到的概念。

A comment to another of my questions says that I can only run "so many" threads concurretnly, a notion which I have seen elsewhere.

作为一个线程的新手，我怎么能确定的最大线程数使用？或者这是一个多久一块字符串的问题？这是什么取决于？硬件配置还是什么？

As a threading novice, how can I determine the maximum number of threads to use? Or is this a "how long is a piece of string" question? What does it depends on? Hardware config or what?

（VB在微软的Visual Studio中与.net 3.5，如果该事项）

更新：有没有人知道任何S / W的工具，它可以建议多个线程（或任务），或者我应该只是code我自己这使尝试不同的数字，直到吞吐量下降。

Update: is anyone aware of any s/w tool which could suggest a number of threads (or tasks), or should I just code my own which keeps trying different numbers until throughput drops?

推荐答案

这取决于硬件你（可能）不使用计算机理论，但在物理硬件之一，所以你只有有限的资源。

It depends on hardware as you're (probably) not using a theoretical computer but a physical hardware one, so you have limited resources.

此外，即使你可以运行5000+的线程，这取决于你的硬件，可以运行超过10线程同等功能的程序慢得多。我想你应该看看线程池。

Furthermore, even if you could run 5000+ threads, depending on your hardware, that could run much slower than a 10 thread equivalent program. I think you should take a look at thread pooling.
