   4  * To use a profiler, copy this file to StartProfiler.php,
   5  * and add either:
   6  *  $wgProfiler['class'] = 'ProfilerXhprof';
   7  *
   8  * For output, add:
   9  *  $wgProfiler['output'] = array( 'text' );
  10  *    'text' can be one (or more) of 'text' 'udp' or 'db'
  11  *    'db' requires creating the profiling table, see patch-profiling.sql
  12  *
  13  * The 'text' output will be added to the output page in a comment approriate
  14  * to the output's mime type. For a text/html page, this display can be
  15  * changed to a preformatted text block by setting the 'visible' configuration
  16  * flag:
  17  *  $wgProfiler['visible'] = true;
  18  *
  19  * The 'db' output expects a database table that can be created by applying
  20  * maintenance/archives/patch-profiling.sql to your database.
  21  *
  22  * For a rudimentary sampling profiler:
  23  *   $wgProfiler['class'] = 'ProfilerXhprof';
  24  *   $wgProfiler['output'] = array( 'db' );
  25  *   $wgProfiler['sampling'] = 50; // one every 50 requests
  26  * This will use ProfilerStub for non-sampled cases.
  27  *
  28  * For performance, the profiler is always disabled for CLI scripts
  29  * as they could be long running and the data would accumulate. Use
  30  * the --profiler parameter of maintenance scripts to override this.
