I would start by using the unix time command.
                                                                        
There is an article in the Feb. 1991 (Vol.9 No.2) issue of Unix Review
called "An Elementary C Cost Model" by Bentley, Kernighan, and VanWyk.
In it, they provide code which measures the amount of time needed for
operations in a C program.  I think this may help you in your task.
Try sending e-mail to David Burnette at uunet!beast!david for the
source code.  I have a copy of the magazine if you want to look at it.

You're welcome.
