* write dump files. The files produced are compatible with the XHProf gui.
* For a rudimentary sampling profiler:
* $wgProfiler['class'] = 'ProfilerXhprof';
- * $wgProfiler['output'] = array( 'ProfilingOutputDb' );
+ * $wgProfiler['output'] = array( 'ProfilerOutputDb' );
* $wgProfiler['sampling'] = 50; // one every 50 requests
* This will use ProfilerStub for non-sampled cases.
