I was recently reading an article that stated that prelinking an executable that makes heavy use of shared libraries can benefit ubuntu. And that Prelinking resolves addresses of shared libraries in advance this reduces number of relocations. It also stated that preloading would significantly increase the speed of ubuntu. I use ubuntu as a server, and services that are constantly running more than loading applications so does this hold any bearing to my context ? I gave it a shot and didnt really see much of a significant difference. Anybody have any thoughts ?

Preload doesn't speed up your system, it speeds up launching applications. This is only really useful for those bloated gui desktop apps like Open Office, Firefox and so on. It's designed to deal with poor responsiveness (which is perceived by the user as poor performance but is actually slightly different) of GNU/Linux on the desktop. A server of course doesn't need to favour applications over services like a desktop does as there's no-one sitting there waiting for a pretty splash screen to disappear. I wouldn't bother with it on a server, though I use preload on my Debian laptops and find it useful.

edit: even where it's useful it doesn't make a difference right away. It watches application launches and favours those most often launched, so it needs to be used for a while to make an impact.
