Thanks for the offer! I could provide you a zip file with all the necessary code to run the test but I don't think its needed.
I distribute this code as an executable (which extracts perl locally and then runs it)

Unfortunately the code will be run on general purpose laptops/desktops,
where I have no control over what is stealing cycles from my process
One of the worst cases I encounter is when I am demoing this code to a prospective customer on a web-Ex
And that really seems to slow the whole process down tremendously

I also distribute this on linux and have been playing with the profiling there to get a more stable result
That VM does give better results varying by 1 or 2 seconds.
Although the very useful nytprofhtml is not working for me on that VM :)

I guess one thing I was hoping someone might tell me that there is a way to
run the perl code as a higher priority windows task
