Detailed Description

Simple interface for displaying request profile data stored in the wikis' primary database.

See also https://www.mediawiki.org/wiki/Manual:Profiling.

To add profiling information to the database:

• set $wgProfiler['class'] in LocalSetings.php to a Profiler class other than ProfilerStub.
• set $wgProfiler['output'] to 'db' to force the profiler to save its the information in the database.
• apply the maintenance/archives/patch-profiling.sql patch to the database.
• set $wgEnableProfileInfo to true.
