CPU线程 [英] CPU by thread

问题描述

有很多例子说明如何获取方法的经过时间，但是我不能找到任何关于如何测量CPU数量的例子由我的

线程在方法中消耗。多线程应用程序中的经过时间，特别是单处理器CPU上的
并不是很有用。


有没有办法测量这个？


谢谢。

Tom

解决方案

Tom，


对于这样的事情，你可以使用PerformanceCounter

类来获得你在任何特定时间点所需的值。


希望这有帮助。

你好Tom，

您最好使用CPU分析器

Google for .NET profiler
http://www.google.co.uk/search?hl=en .. .er& btnG =搜索


这些擅长识别瓶颈。

唯一的问题是你需要有测试用例确切地说，用户正在做什么，以便能够使用

euivalent数据量来调用正确的方法。


通常，你可以瞄准调整10种最慢的方法和10种最常用的
经常被称为方法。

There are many examples of how to get the elapsed time for a method but I
can''t find any example of how to measure the amount of CPU consumed by my
thread in a method. Elapsed time in a multithreaded application particularly
on a single processor CPU is not very useful.

Is there a way to measure this?

Thanks.
Tom

解决方案

Tom,

For something like this, you could probably use the PerformanceCounter
class to get the values that you need at any particular point in time.

Hope this helps.

Hello Tom,
You might be better off using a CPU profiler
Google for .NET profiler
http://www.google.co.uk/search?hl=en...er&btnG=Search

These are good at identifying the bottlenecks.
The only issue is that you need to have test cases to do exactly what
the users are doing to be able to invoke the correct methods with
euivalent amount of data.

Typically, you can aim at tuning 10 slowest methods and 10 most
frequently called methods.

I have seen it here but can''t remember where is it exactly. Have a try:
