Prelinking Guide- Make Ubuntu Feel Faster

[Leif]

I am asking this because if it can speed up the system why isn't the ubuntu gets installed prelinking enabled off the bat and I would prefer the stability of ubuntu over the performance under any condition.

I tried prelinking in hoary, on two different systems, and each time something went wrong. I was able to un-prelink, but I did have a couple of minutes where everything was very broken.

Right... what is something goes wrong ?

I mean... what happens if prelink brokes everything ?
And... is it possible undo to fail ?


Last question: is there a way to prelink (and keep prelinked) just a few applications ?

Let's say firefox, openoffice and some more ? (I know tehre was ooprelink, but what a about other apps ?)

[steffen]

Any way of prelinking openoffice.org2 only? That's the only app that takes ages to load, even with my tweaked memory settings in the prefs.

As far as I can see, the ooqstart only preloads ooo1, not 2

Prelinking my system breaks the postfix package, and then I have some messages like
ldconfig: /usr/lib/libpostfix-util.so.1 is not a symbolic link

ldconfig: /usr/lib/libpostfix-global.so.1 is not a symbolic link

You should ask one of the devs at http://opensuse.org as they have prelinked only the KDE base, KDM, OOo, Mozilla, Firefox, and a couple other things in SuSE 10.0.

But, the prelinking added about 30-45 sec. to the startup and shutdown and for some reason, it didn't seem to do much. OOo 2.0 runs faster un-prelinked here in Ubuntu than it did with pre-linking in SuSE.

installing and uninstalling programs seems to be slower than before, waiting for prelinking to finish tooks time to finish

Thats the only downside but if you use apt-get it is faster with prelink has something to do with the was the console is implembented in the dialouge some how
but its ok with me tho it still get the job done

So please comment about this if you have experience from hoary or breezy's preview release. Thanks

I found the hard disk 'grind' from prelink and the resulting slowdown pretty annoying (esp. on laptop), outweighing small loadup time improvements. Some instability too, but I can't tell if that's linked to prelink.

PS The best way to speed up OpenOffice is to use Abiword/Gnumeric instead

Works great on an ancient Clamshell iBook!
Got a bit worried about the time it took for the initial prelink session, though, heehee. Took ages.
on a slower machine, the speedup is quite spectacular, thanks a lot!

Prelinking my system breaks the postfix package, and then I have some messages like
ldconfig: /usr/lib/libpostfix-util.so.1 is not a symbolic link

ldconfig: /usr/lib/libpostfix-global.so.1 is not a symbolic link
I can get rid of these by reinstalling postfix, but another prelink make them come back

please any ideas ?
