3 * Simple interface for displaying request profile data stored in
4 * the wikis' primary database.
6 * See also https://www.mediawiki.org/wiki/Manual:Profiling.
8 * To add profiling information to the database:
10 * - set $wgProfiler['class'] in LocalSetings.php to a Profiler class other than ProfilerStub.
11 * - set $wgProfiler['output'] to 'db' to force the profiler to save its the
12 * information in the database.
13 * - apply the maintenance/archives/patch-profiling.sql patch to the database.
14 * - set $wgEnableProfileInfo to true.
