I was primarily thinking about your testbench.

Perhaps I don't understand what you're asking. What would you like to
use on a clean strace log?

The only thing that my testbench does currently is to add a comment on
every _lseek, read and write line showing cumulative efficiency on that
file descriptor, along with the position of the drive heads at the time
the read/write call was made. These two pieces of information are only
used to plot the fancy graphs I've shown.

You can certainly derive the same plots from a clean strace log, which
contains all the necessary information.

Well, basically I would like to run the kinds of test that you did, but on darwin. ang generate the graphs to see if any changes I've made improves any performance.
