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。

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.

如果你正在寻找一些快速，简单，免费的东西，http://code.google.com/p/slimtune/似乎做的很好。

不要忘记nProf -一个非常好的免费分析器。

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

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:-)
