Linux Preload is a Linux daemon that stores commonly-used libraries and binaries in memory to speed up access times; similar to Windows Vista's SuperFetch function. This article looks at Preload and gives some insight into how much performance is gained for its total resource cost.

I always thought that disk cache was meant to speed up operating system and applications performance? Why use "prefetch" and waste disk cache now?

What the point of copying libraries TWICE (first time prefetch and second actual launch)- you do run application from hard drive, not from memory I presume.
