我一直在使用JetBrains dotTrace用于WinForms和控制台应用程序(尚未在ASP.net上测试)，它工作得很好:

他们最近还增加了“个人许可证”，比企业许可证便宜得多。不过，如果有人知道一些更便宜甚至免费的，我也想听听:-)

Intel®VTune™性能分析仪快速采样

如果你是ASP。你可以尝试MVCMiniProfiler (http://benjii.me/2011/07/using-the-mvc-mini-profiler-with-entity-framework/)

当前版本的SharpDevelop(3.1.1)有一个很好的集成分析器。它非常快，并且很好地集成到SharpDevelop IDE和它的NUnit运行器中。结果以灵活的树/列表样式显示(使用LINQ创建自己的选择)。双击显示的方法将直接跳转到源代码。

我想添加yourkit java和。net profiler，我喜欢它的java，但还没有尝试过。net版本。

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. Checkout this page for details.
