MemTurbo - Version 1.5 Get that "just-booted" feeling with a single keystroke! The safe, easy, and effective way to increase your system performance. Defragments physical RAM, recovers RAM from the operating system and applications, recovers leaked memory, and fine-tunes file caching to your specific usage scenarios. Does NOT use compression, nor does it install any drivers or VxDs, or anything outside of its own directory.
