from 'man prelink' |

'prelink is a program that modifies ELF shared libraries and ELF |
| 14 |
dynamically linked binaries in such a way that the time needed for the |
| 15 |
dynamic linker to perform relocations at startup significantly |
| 16 |
decreases. Due to fewer relocations, the run-time memory consumption |
| 17 |
decreases as well (especially the number of unshareable pages). The |
| 18 |
prelinking information is only used at startup time if none of the |
| 19 |
dependent libraries have changed since prelinking; otherwise programs |
| 20 |
are relocated normally.' |

So I would not expect much gain from fast storage such as an SSD, and |
| 23 |
also the linker would hopefully have gotten smarter as well, perhaps |
| 24 |
making prelink redundant. From an "average system" some time ago when |
| 25 |
prelink first hit gentoo, it made a huge difference in startup times on |
| 26 |
the likes of openoffice when I did timimgs. |

All my systems are prelinked these days, and I have not the time to do |
| 29 |
any tests - is someone able to do before/after tests on some common, but |
| 30 |
slow loading apps and post here? |

Settle this one way or another :) |
