Showing my ignorance.  Is there a posted standard for Drupal performance testing?  The last time I did some tests, I just used apache benchmark (copying something I had seen Killes do previously).

Simpletest and the wget method (http://drupal.org/node/11521) don't seem to cover overall performance.
