The prelims:  We are a .NET shop.  We generally, though not always work in ASP.NET 2.0.  We do consulting.

Ok, now, I very OFTEN get asked "Will the site you build us support 200 users at once?"  So, since we're fairly new and we haven't put in place every part of our company we really haven't done any metrics type testing.

I am looking for suggestions on web load testing, web unit testing.  Product votes + or -, notes, comparisons, likes, dislikes, etc.  Some of the ones I've stumbled upon include:

Visual Studio for Testers
Empirix
NeoLoad

Anyone know of other ones?

Visual Studio 2005 has a built-in performance tool in the test edition.

You can create your own multi-threaded C# app using HttpWebRequest objects.

Mercury Interactive has something called LoadRunner.

Microsoft has something called Homer, WAST, or whatever it's called now.

And now you have to define what 200 users means.


Does it mean 200 users actively using the site. Or does it mean 200 page loads per second. Completely different.

I want my scalps!
Here's a little warning for you. A few years ago we wanted to load test our web application. Of course, we forgot about our firewall (separate Linux-based machine). As soon as we started the load test, the firewall detected an "attack" and decided to block all traffic to our server. Luckily, it was a test server, so not much harm was done.

may i suggest apache's ab2? (ab2 and lucene are the 2 most usefull things come out of apache project, apache server itself is dead/slow as dodo)

to test your web app, the fact that its .net app shouldnt make much difference as there are extensive options available


thanks to the above and extensive code profiling, our 3 large php based sites are handling 1million page views / 300k uniques a day on one front end server running lighttpd and php5

If your web application is complex (AJAX, Silverlight etc.) I recommend iMacros Web Testing, it works well for our performance monitoring.
