from 'man prelink' 'prelink is a program that modifies ELF shared libraries and ELF dynamically linked binaries in such a way that the time needed for the dynamic linker to perform relocations at startup significantly decreases. Due to fewer relocations, the run-time memory consumption decreases as well (especially the number of unshareable pages). The prelinking information is only used at startup time if none of the dependent libraries have changed since prelinking; otherwise programs are relocated normally.' So I would not expect much gain from fast storage such as an SSD, and also the linker would hopefully have gotten smarter as well, perhaps making prelink redundant. From an "average system" some time ago when prelink first hit gentoo, it made a huge difference in startup times on the likes of openoffice when I did timimgs. All my systems are prelinked these days, and I have not the time to do any tests - is someone able to do before/after tests on some common, but slow loading apps and post here? Settle this one way or another :) Billk -- William Kenworthy <bi...@iinet.net.au> Home in Perth!
