如果许可是一个问题，您可以尝试WINDBG进行内存分析

我怀疑Visual Studio Team System自带的分析器是不是最好的分析器，但我发现它在很多情况下已经足够好了。除了维密所提供的，你还需要什么?

编辑:不幸的是，它只在VS团队系统中可用，但如果你有机会，它值得一试。

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.

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:-)

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。

我还要补充一点，dotTrace区分内存和性能跟踪会话的能力绝对是无价的(ANTS可能也有内存差异特性，但我没有看到性能差异)。

能够在bug修复或增强之前和之后运行一个分析会话，然后比较结果是非常有价值的，特别是对于一个庞大的遗留的。net应用程序(就像我的情况)，性能从来都不是优先考虑的，而且查找瓶颈可能非常乏味。执行前后差异可以查看每个方法的调用计数变化和每个方法的持续时间变化。

This is helpful not only during code changes, but also if you have an application that uses a different database, say, for each client/customer. If one customer complains of slowness, you can run a profiling session using their database and compare the results with a "fast" database to determine which operations are contributing to the slowness. Of course there are many database-side performance tools, but sometimes I really helps to see the performance metrics from the application side (since that's closer to what the user's actually seeing).

总结:dotTrace工作得很好，差异是无价的。
