在过去，我使用Visual Studio Team System附带的分析器。

The NuMega True Time profiler lives on in DevPartner Studio by Micro Focus. It provides line and method level detail for .NET apps requiring only PDBs, no source needed (but it helps.) It can discriminate between algorithmically heavy routines versus those with long I/O waits using our proprietary per thread kernel mode timing driver. Version 10.5 ships with new 64-process support on February 4, 2011. Shameless plug: I work on the DevPartner product line. Follow up at http://www.DevPartner.com for news of the 10.5 launch.

免责声明:我是microfocus开发伙伴的产品经理。

对我来说，SpeedTrace是市场上最好的工具，因为它不仅能帮助您找到应用程序中的瓶颈。它还可以帮助你在故障排除场景中找到为什么你的应用程序崩溃，你的安装没有安装，你的应用程序挂起，你的应用程序性能有时很差取决于数据输入，例如，识别缓慢的db事务。

我最近发现了EQATEC Profiler http://www.eqatec.com/tools/profiler。它适用于大多数。net版本和许多平台。它易于使用，部分内容是免费的，即使用于商业用途也是如此。

I must bring an amazing tool to your notice which i have used sometime back. AVICode Interceptor Studio. In my previous company we used this wonderful tool to profile the webapplication (This is supposed to be the single largest web application in the world and the largest civilian IT project ever done). The performance team did wonders with the help of this magnificent tool. It is a pain to configure it, but that is a one time activity and i would say it is worth the time.

蚂蚁分析器。我用过的不多，但我对ANTS并没有什么抱怨。可视化真的很有帮助。
