Procedure profiling in Application Profiling mode

This section explains how to use the Application Profiling mode in Sybase Central to perform procedure profiling. It is the recommended method for accessing procedure profiling results. However, you can also use SQL statements to perform procedure profiling.

Procedure profiling shows you how long it takes your procedures, user-defined functions, events, system triggers, and triggers to execute. You can also view line-by-line execution times for these objects, once they have run during profiling. Then, using the information provided in the procedure profiling results, you can determine which objects should be fine-tuned to improve performance within your database.

Procedure profiling can also help you analyze specific database procedures (including stored procedures, functions, events and triggers) found to be expensive via request logging. It can also help you discover expensive hidden procedures, for example, triggers, events, and nested stored procedure calls. As well, it can help pin-point potential problem areas within the body of a procedure.

Procedure profiling results are stored in memory by the database server. Profiling information is cumulative, and accurate to 1 ms.
