1. JMeter (time taken:        )

   a. Setup JMeter
      Download JMeter (e.g., jakarta-jmeter-2.0.1_bin.zip) from the Java Apache
      Project web site (http://jakarta.apache.org) and install it by extracting
      the zip-file. (See also: Documentation - User Manual - 2.3 Installation.)

   b. Creating and running tests
      Create and run a test for a Web page: Follow the description in the JMeter
      User Manual, section 3 and 5 Building a Web Test Plan. Run the test with
      the settings given in the example, (5 users) x (2 requests) x (repeat 2 
      times) = 20 HTTP requests.

   c. Analyzing results
      Add following listeners to your test: Graph Results, View Results Tree, 
      Aggregate Report, and View Results in Table. Compare the visualization 
      they provide - which is the most useful. (See also: 15.3 Listeners in the 
      User Manual.)

      what you consider good/bad quality and what should count as bug, e.g.,
      pages that fail in terms of functionality, usability, robustness,
      performance, security, etc. Check your favorite sites for such bugs ...

   c. Report one of the bugs you found into the Bugzilla bug tracking system.
      Provide a concise summary line, the URL of the page you found the bug, a
