Profiling support has been added in the MySQL versions 5.0.37 and 5.1.28. We have previously seen the Profiling checkbox appear in query results.

When this box is checked, phpMyAdmin will analyze every query (including the current one), and a report about the execution time of each MySQL internal operation is displayed as shown in the following screenshot:

Although the profiling system can report additional information about operations (such as the CPU time, and even the internal server's function names), phpMyAdmin currently displays only the name of the operation and its duration.
