最大线程数 [英] The maximum number of thread

问题描述

在Delphi中开发的32位和64位应用程序中最大线程数是多少？

What is the maximum number of thread in an application 32-bits and 64-bits developed in Delphi?

我需要知道运行线程的限制是多少同时在32位应用程序上运行，因为我正在执行性能分析，并且希望让OS管理正在等待的线程的执行顺序。

I need to know what is the limit of threads running simultaneously on a 32-bit application, because I'm doing performance analysis and I want to let the OS manage the execution order of the threads that are waiting.

还是，我在我在上面的评论保持部分正确（但也请注意马丁·詹姆斯（Martin James）对此的反对意见）。

Still, what I wrote in my comment above stays partially true (but please also notice Martin James' objection to it below).

请注意-一般而言，如果创建的线程数多于
个处理器内核（或虚拟等效物），您将不会获得任何
的性能优势。如果创建过多，甚至会得到
这样的非常糟糕的结果：

您将需要理论上可能的最大线程数？

Notice that - generally speaking - if you create way more threads than processor cores (or virtual equivalents), you will not gain any performance advantage. If you create too many, you'll even end up with pretty bad results like these: thedailywtf.com/Articles/Less-is-More.aspx So are you completely sure that you'll need the theoretically possible maximum number of threads?
