Manual:Profileinfo.php/es

Detalles
Allow users to see the profiling information that are stored in the database.

To save the profiling information in the database (required to use this script), you have to modify StartProfiler.php to use the Profiler class and not the stub profiler which is enabled by default. You will also need to set  correctly in  to force the profiler to save the informations in the database and apply the maintenance/archives/patch-profiling.sql patch to the database.

To enable the profileinfo.php itself, you'll need to set  to true in LocalSettings.php. See also the help on profiling.
