在过去，我使用微软Web应用程序压力测试工具和Pylot对Web应用程序进行压力测试。我写了一个简单的主页、登录脚本和站点演练(在一个电子商务网站中添加一些商品到购物车和结帐)。
只要让少数开发人员在主页上使劲敲一下，就几乎总能找到一个主要问题。更多的可伸缩性问题将在第二阶段浮出水面，甚至更多——在发布之后。
我使用的工具的URL是Microsoft Homer(又名Microsoft Web Application Stress Tool)和Pylot。
这些工具生成的报告对我来说没有多大意义，我花了很多时间试图弄清楚站点能够支持什么样的并发负载。这总是值得的，因为最愚蠢的错误和瓶颈总是会出现(例如，web服务器配置错误)。
你做了什么，你使用了什么工具，你的方法有什么成功?对我来说，最有趣的部分是提出某种有意义的公式，用于从压力测试应用程序报告的数字中计算应用程序可以支持的并发用户数。

这是给JMeter的另一票。
JMeter是一个开源的负载测试工具，用Java编写。它能够测试许多不同的服务器类型(例如，web, web服务，数据库，基本上使用请求的任何东西)。
然而，一旦你开始面对复杂的测试，它确实有一个陡峭的学习曲线，但它是非常值得的。您可以非常快速地启动并运行，这取决于您想要进行哪种类型的压力测试，这可能没问题。
优点:
Open-Source/Free tool from the Apache project (helps with buy-in) Easy to get started with, and easy to use once you grasp the core concepts. (Ie, how to create a request, how to create an assertion, how to work with variables etc). Very scalable. I've run tests with 11 machines generating load on the server to the tune of almost a million hits/hour. It was much easier to setup than I was expecting. Has an active community and good resources to help you get up and running. Read the tutorials first and play with it for a while.
缺点:
The UI is written in Swing. (ugh!) JMeter works by parsing the response text returned by the server. So if you're looking to validate any sort of javascript behaviours, you're out of luck. Learning curve is steep for non-programmers. If you're familiar with regular expressions, you're already ahead of the game. There are large numbers of (insert expletive) idiots in the support forum asking stupid questions that could be easily solved if they'd give the documentation even a cursory glance. ('How do I use JMeter to stress-test my Windows GUI' shows up quite frequently). Reporting 'out of the box' leaves much to be desired, particularly for larger tests. In the test I mentioned above, I ended up having to write a quick console app to do some of the 'xml-logfile' to 'html' conversions. That was a few years ago though, so it's probable that this would no longer be required.

我用过Grinder。它是开源的，非常容易使用，并且非常可配置。它是基于Java的，脚本使用Jython。我们在一个。net web应用程序上运行了它，所以不要认为它只是一个Java工具(从本质上讲，任何web压力工具都不应该与它所使用的平台绑定)。
We did some neat stuff with it... we were a web based telecom application, so one cool use I set up was to mimick dialing a number through our web application, then used an auto answer tool we had (which was basically a tutorial app from Microsoft to connect to their RTC LCS server... which is what Microsoft Office Communicator connects to on a local network... then modified to just pick up calls automatically). This then allowed us to use this instead of an expensive telephony tool called The Hammer (or something like that).
无论如何，我们还使用该工具来查看应用程序在高负载下的运行情况，它在查找瓶颈方面非常有效。该工具内置了报告，以显示请求花费的时间，但我们从未使用过它。日志还可以存储所有响应或自定义日志。
我强烈推荐这个工具，非常有用的价格…但是期望用它做一些自定义设置(它有一个内置的代理来记录脚本，但它可能需要自定义来捕获会话之类的东西……我知道我必须自定义它以利用每个线程的唯一会话)。

尝试了这里提到的所有方法，我发现卷曲加载器最适合我的目的。非常简单的界面，实时监控，有用的统计数据，从中我建立了性能图表。libcurl的所有特性都包含在内。
我赞成开放的建议。我只想补充一点，它允许您使用SMTP来监视您正在测试的服务器。我们跟踪处理器负载、内存使用、发送的byes等等。唯一的缺点是，如果你发现某些东西有问题，想要修复它，它依赖于几个不再保持的开源库，所以获得源代码的编译版本比大多数OSS更棘手。
看一下TestComplete。
