Samba and Application Response Measurement (ARM 4.0)

Is there any technical documentation where i can find which part of the
source code (or function) is responsible for:

- user authentication (to PDC)
- loading the user profile
- mounting paths and printers

As these are the parts we are most interested in measuring. Looking at the
source code, i can see the different files involved in the mentioned
processes, but it is difficult to pinpoint the right locations for the ARM
transactions (i.e. the right functions).

Best regards
