Does Ready Boost Improve FPS

Ready boost has been around years, but does it do anything but destroy USB sticks? That's the question I have been asking myself. So I decided to put it to the test. I ran the video stress test feature on Source SDK base 2006 with and without the stick. Here is my results:

With Stick: 82.51

Without Stick: 90

From our results, it appears that the USB stick actually decreased the FPS achieved. The same peripherals, software and conditions were present for each test. The decrease is likely just due to how the video stress test works, but this proves that READY BOOST DOES NOT BOOST FPS.
