"Via Windows ReadyBoost, Windows Vista can increase performances in correlation with a USB key. Vista will use the USB Drive to compensate for memory shortage or to simply boost speed, by creating a copy of the virtual memory on 230 MB free space on the flash drive.
Vista does not increase the system RAM on the machine, but through ReadyBoost, it stores information that is repeatedly accessed by the memory manager. In this context, the operating system accesses the data stored on the flash drive instead of randomly accessing the disk. Vista features like data indexing, the Aero graphical user interface and the desktop window manager tend to take up extra memory. ReadyBoost balances functionality and memory management.
HT203 ReadyBoost testing:
- Calculate system response time (seconds) with/without ReadyBoost enabled while first execute each program from the beginning to ready for working.
- The difference between the tests smaller or equal than 2 seconds were treated as reasonable, such values were neglected.
- The numbers in brackets are the performance improved rate.
