AutomatedQA AQTime计时和SciTech MemProfiler内存。

我以前跟红门的侧写师合作过。帮我完成了任务。

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。

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.

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.
