Nothing all that complicated really.
It's more bureauocratic ca-ca than anything else.
But they would like to see that I ran some kind of 'metric' and kluged some data together to show that the code itself is reasonably well written and efficient.
I can make the data do what I want it to do, I'm just looking for some way to get some data that I can use in this case.

There will be a comparison to a previous 'version' of what I'm now writing. But that version was written by $someone_else, and therefore not much my concern. What I've written runs a touch slower, but provides significanly better results. And it's the better results that needs the bigger play. I just need to show some kind of numbers on the relative speed of both programs. If need be, I can outright 'fudge' numbers with a stopwatch. I'm just looking for something technical enough that I can make a manger's eyes glaze over. :)
