no, not that it is supposed to be really fast... but it isn't what  
gets in your way.

My guess is that your test is slow. To start, take rake out of the  
equation:

	ruby -rtest/unit test/unit/user_test.rb

After that, you can do something simple like:

   def setup
     @start_time = Time.now
   end

   def teardown
     puts "** TIME: #{self.name} : #{Time.now - @start_time} seconds
   end

And see what's going so slow a little clearer.

I run thousands of tests/assertions in just seconds many times a day:

ruby:  Finished in 0.105172 seconds. 252 tests, 735 assertions, 0  
failures, 0 errors
ruby:  Finished in 1.275824 seconds. 750 tests, 2220 assertions, 0  
failures, 0 errors
rails: Finished in 81.681246 seconds. 1924 tests, 12195 assertions, 0  
failures, 0 errors
