Libraries for Benchmarking

Libraries for Benchmarking

This appendix describes two libraries that can help with all of the tasks just mentioned:

libpdb (Performance DataBase). Routines for measuring execution rates and maintaining a simple database.
libisfast. A set of routines demonstrating libpdb that answer common questions about the performance of OpenGL features (using reasonable but subjective criteria).

These libraries can't substitute for comprehensive benchmarking and performance analysis, and don't replace more sophisticated tools (like IRIS Performer and IRIS Inventor) that optimize application performance in a variety of ways. However, they can handle simple tasks easily.
