The patients were identical Toshiba Satellite A15-S129 laptops with 256MB of RAM and a 2.4GHz Celeron processor.
First step was to remove all the extra crap from the Startup menu, and use msconfig to disable everything else that didn't look neccessary.
Next step was to define a benchmark meaningful to the user. In this case, they use Photoshop Elements 5, so I added the trial version of that app to the startup menu, and measured how long it took from poweron to the license prompt for Photoshop.
I then ran that benchmark with the original 256MB, then with 512MB, and finally 768 MB. Results:
|poweron to license prompt||404 sec||226 sec||205 sec|
Here's the detailed data (wall clock time, minutes and seconds):
