Web Load Testing with Fiddler

If you have been in the web business long, you've got to love Fiddler.  There is so much packed into a little package.  It can save you hours of debugging -- if you know how to use it.

Here's a new load test feature (at least it's new to me.)  Basically, in the Results window, select any request or set of requests, then press CTRL-R.  This will bring up a dialog box asking for how many times you want to run the command.  Enter your test count, press OK and let the barrage begin!

While there isn't too much instrumentation, there is a fair amount.  If you select the Timeline tab you can get an idea of concurrent transfers.  And the Statistics tab gives you performance information.

I was recently performance testing a web server application.  I used this technique in conjunction with Perfmon and was able to get some deep statistics.

Try it out and let me know how it works!
