It was suggested to me that Perl has a nanosecond timer function that could be of use.

Whoever suggested such was probably referring to Time::HiRes. The granularity you actually get is, of course, system defined.

In addition to the Devel:: modules Ovid mentioned, the Benchmark module might be helpful. Maybe.

The other advice Ovid gave you was right on. Find out what the client wants. What would constitute '"proof" of efficiency' in client's mind? Try to nail that down right away; otherwise, you may be in for some headaches.
