Along with my pioneering use of indexes, a bug in the core Database class was revealed. I have fixed the class and the fixes are available here:
0.9.3-1 users: http://leaguesite.sf.net/Database0931.zip
0.9.3-2 users: http://leaguesite.sf.net/Database0932.zip
NOTE: If you downloaded the "supplemental" zip package after January 5, 2003, then the new Database.php was included in that and you shouldn't need to download a new one.
Sorry for the inconvenience but the use of indexes will greatly improve LeagueSite database performance.
