I've posted the slides from today's Sphinx talk at Vancouver Drupal Camp.
Ianiv of NowPublic pointed out that while Sphinx is quick to search, its updating speed is less than that of Xapian, another C++-based search engine. Nonethess, Sphinx is going to dramatically increase speed and search quality for the vast majority of sites.
The example Drupal module employing Sphinx, referred to in the talk, can be downloaded here.
