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.

There's a difference between having a library in disk cache, and having it actually loaded and mapped in to the system. In theory, once the library is loaded and mapped, at that point it can only take VM space (not necessarily physical memory space). Which basically comes down to if the library is swapped out, is that better, worse, or the same as having the library not loaded at all. That I don't know, and I don't know if any of this has actual impact on the user experience.
