Microsoft发布了最新版本的PerfView，它修复了一些小错误并增加了对Microsoft .NET 4.5的支持。Microsoft开发了这些工具，用于为应用程序开发人员分析和隔离与CPU或内存^(Memory)相关的性能问题。它将帮助您缩小导致性能问题的函数或线程的范围并指向源代码，以便您可以优化它或修复该特定部分中的任何错误。

PerfView是一个性能分析^{(Performance Analysis)}和分析工具^{(Profiling Tool)}

与其他一些工具不同，我发现Microsoft的^(Microsoft)PerfView对用户非常友好，为用户提供大量超链接信息，以了解其工作原理。Microsoft已包含一个Tutorial.exe文件；试一试，看看它是如何工作的。该工具使用Windows事件^(Windows)跟踪^{(Event Tracing)}( ETW ) 功能来分析和转储数据。在为您的程序解决与性能相关的问题时，它非常有用。

该工具基本上通过中断CPU来获取堆栈的快照。强烈建议阅读教程^(Tutorial)部分和工具中提供的指南，以更好地了解该工具。

默认情况下，它需要所有进程的堆栈 - 但您可以选择要排除故障的EXE文件。^(EXE)如下图所示，它告诉您堆栈集合中每一帧的名称，以及CPU的总成本和总成本。

这样，故障排除就容易多了，它可以帮助您找出堆栈中的哪个帧可能导致CPU使用问题并查明问题的根源。您还可以定义Symbol服务器，以便它下载它并在本地缓存它。

它是应用程序开发人员更有效地缩小和查明与性能相关的问题的好工具。如果您是应用程序开发人员，请务必查看PerVeiw；它肯定会帮助你。您可以从github.com下载它。

PerfView is a Performance Analysis & Profiling Tool from Microsoft

Microsoft has releаsed the latest verѕion of PerfView, which fixes minor bugs and adds support for Microsoft .NET 4.5. Microsoft has developed these tools for analyzing and isolating CPU or Memory related performance issues for application developers. It will help you narrow down the function or thread, which is causing the performance problem and point to the source code so that you can optimize it or fix any bugs in that specific section.

PerfView is a Performance Analysis & Profiling Tool

Unlike some other tools, I have found PerfView from Microsoft, to be very user-friendly with tons of hyperlinked information for the user, to understand how it works. Microsoft has included a Tutorial.exe file; try it and see how it works. The tool uses the Event Tracing for Windows (ETW) feature to analyze and dump the data. It’s very helpful while troubleshooting performance-related problems for your program.

The tool basically takes snapshots of the stacks, by interrupting the CPU. It is highly recommended to read the Tutorial section and the guides provided within the tool, to understand the tool better.

By default, it takes the stack of all the processes – but you can choose the EXE file that you want to troubleshoot. As you can see in the image below, it tells you the name of each frame in the stack collection, with the total cost of the CPU and the total amount of the cost.

This way, the troubleshooting is a lot easier, and it helps you find out, which frame in the stack could be causing the CPU usage problems and pinpoint the source of it.  You can also define the Symbol server so that it downloads it and caches it locally.

It is a great tool for application developers to narrow down and pinpoint performance-related problems, more effectively. If you’re an application developer, be sure to check out PerVeiw; it will certainly help you. You can download it from github.com.
