Profiling MiniSIP

[Xuan Pan]

I know little about Gprof. As an alternative, the timestamp facility in
libmutil library is a very helpful tool when measuring the execution time
of a function call or recursive calls. All you need to do in the code is
to identify the security relevant functions. Add ts.save() right before
and after the function call.

The following steps may help you to get the results:

1. When you configure the library, you need to use -DENABLE_TS to enable
the timestamp functionality.

2. Secondly run minisip

3. kill -USR1 MINISIP_PID

4. less /proc/minisip_ts

There are links of a number of master or PHD thesis that contain
performance measurement as the last step in their research. Could be very
helpful references too.
