Industry:
ConsumerSearch.com has been redesigned and is now running Drupal. The site is a part of the About.com Group, a subsidiary of The New York Times Company.
ConsumerSearch.com gets about 5.5M unique visitors each month (and growing). I don't know what server infrastructure they run on, but with the help from Jeremy at Tag1 Consulting, they configured Drupal to rely heavily on memcached and Drupal's built-in aggressive caching mode. Knowing Jeremy, they are probably trying to serve cached pages from disk, rather than from the database.
