Lisp performance data

[vlion]

My code has run real slow for my thesis.

But, I noticed something odd last night. My code was running faster the more I ran it. Obviously something was being cached...
With a little digging

* (time (render-trace "../../programs_of_interest/one-transfer"))

Notice the page faults! They really sucked up the time.
