A recent visit to TomsHardware brought two pages to my notice... Windows XP vs. Vista: The Benchmark Rundown & Windows Vista's SuperFetch and ReadyBoost Analyzed Wanted to share it with my friends here... Regd. the XPvsVista analysis, bottomline(as the pro's can tell)'s that programs like encoding, transcoding & other workloads'll run slower in Vista but the overall performance'll look smoother & faster, thanks to Superfetching & ReadyDrive. Regd the latter... SuperFetch analyzes your behavior and proactively puts applications into available main memory, so they can be launched quicker. Of course this requires as much main memory as possible, which is where the second feature engages. ReadyBoost is the memory extension for the Superfetching feature of Vista. It allows adding more memory to the system, a la the swap file, via expanding the main memory size with the intended swap storage device being the cheaper & reasonably fast USB 2.0 Flash drive, instead of more RAM. The reason being.. Flash Drives r faster than HardDisks. All said & done in a few words, I'll like u 2 look into the pages too for more info. A must-read for all enthusiasts. Really informative. __________ NOTE I'ld also like to add a bit of info about a method I've been using from quite sometime... and it really works. Even XP users can use the ReadyDrive feature. How? By customizing the virtualRAM properties and making ur USB 2.0 stick as a storage device/drive for virtual RAM/Swap file, u can actually emulate the ReadyDrive feature of Vista. Not exactly ReadyDrive technology, but move the whole swap file to the USB... instead of using the slower harddisk for VRAM.
