- Profiling the Second Life client code on Linux.
- Profiling is use to determine how much CPU cycles are being used by parts of your code.
- The GCC compiler has a flag which adds extra code to the binary during compilation. The purpose of the extra code is to record the entry and exit from a procedure. When the program exits the information is written to a file. (usually call gmon.out) This information is then post processed to show you how much process time is spent in each routine.
- "Gprof" calculates the amount of time spent in each routine. Next, these times are propagated along the edges of the call graph. Cycles are discovered, and calls into a cycle are made to share the time of the cycle.
- The end goal of course is to speed up the code.
