/**
|
||
* 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.
