You didn't have the test I really wanted to see, compile an application, like (for example) the Linux kernel. Actually, what I really want to see is how long it takes to load up the test suite (something that happens before every test is run) in a Ruby on Rails application. I found that having to wait several seconds for it to load up on a slow 5400rpm drive really slowed down my development, especially since I develop in a test-first manner. But I can't expect you to do something so specialised. But compiling a Linux kernel is similar, and much more relavent to most Linux users.
