VB程序中的处理器使用情况 [英] Processor usage in VB program
问题描述
我正在写一个VB.Net 1.1应用程序，它必须通过
TCP / IP来收听消息。
当一个到达它排队，然后在一个单独的线程处理，而
主线程回去听更多。
当我看到任务管理器时，它表明该程序占用处理器的100％
，除非另一个应用程序需要运行。这是正常的吗？请
我需要担心吗？如果有的话有没有办法修改主要的听力任务
这样它就没有使用这么多的资源呢？
我还是挺的VB.Net的新手，所以请尽量保持简单！
谢谢
I''m writing a VB.Net 1.1 app that has to listen for messages coming to it via
TCP/IP.
When one arrives it it queued and then processed on a seperate thread while
the main thread goes back to listening for more.
When I look at the Task Manager, it shows that the program is taking up 100%
of the processor unless another application needs to run. Is this normal? Do
I need to worry? If so is there any way of modifying the main listening task
so that it is not using so much of the resources?
I''m still quite new to VB.Net so please try to keep things simple!
Thanks
推荐答案
<循环中的
，尝试在某处插入System.Threading.Thread.Sleep（sleepTimeInMs）
（通常在循环结束之前）...它可能会
帮助...
我希望它有所帮助

Hi,
in your loops, try to insert a System.Threading.Thread.Sleep(sleepTimeInMs)
somewhere (usually just before the end of the loop)... it will probably
help...
I hope it helps

主线程会回到监听更多。
当我查看任务管理器时，它显示该程序占用处理器的100％，除非另一个应用程序需要运行。这是正常的吗？
the main thread goes back to listening for more.

不，不正常。一个线程或另一个线程消耗cpu周期，你需要修复它。
需要修复它。我建议你不要启动工作线程 - 让主要的
线程继续排队并让队列增长。如果你仍然盯着
100％，那么罪魁祸首就是主线，如果没有，罪魁祸首是工人
线程。
在任何情况下，问自己的问题是：当什么都没有时，
开启，线程在做什么？应该用
阻止所有线程，这样系统空闲进程几乎100％挂钩。应该阻止主线程
监听传入数据。工作线程应该在主要的
线程的控制下运行或阻止。
No, not normal. One thread or the other is consuming cpu cycles, and you
need to fix that. I suggest you not start the worker thread - let the main
thread keep enqueuing and let the queue grow. If you are still pegged at
100%, then the culprit is the main thread, if not, the culprit is the worker
thread.
In any case, the question to ask yourself is this: when nothing is going
on, what are the threads doing? All threads should be blocked by something
so that the system idle process is pegged at nearly 100%. The main thread
should be blocked listening for incoming data. The worker thread should
either be not running or blocked on something under the control of the main
thread.

我对VB.Net还是很新的所以请试试保持简单！

不，这不正常。
你能发一个简短但完整的程序这表明
问题？

No, that''s not normal.
Could you post a short but complete program which demonstrates the
problem?
See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.
