Preload is great, try it to speed up your applicaiton launch time.

[Caleb Marcus]

According to my friend, my last message didn't display properly...
something about the text wrapping. I'm
resending, with manually inserted line breaks.

I was IMing a friend who told me about preload, a daemon that figures
out which apps you use most and
caches their executables and libraries into RAM. Because GNOME login and
application launch cause
nonsequential disk reads (and thus, a lot of seeks) it's extraordinarily
helpful to read in a bunch of libraries in
advance, linearly, so that when you go to launch the app, everything's
already in RAM. I've installed it, and it's
drastically improved the time it takes to log into Gnome (I have a lot
of startup applicaitons), the time it takes
to launch OpenOffice.org (It's seriously about as fast as AbiWord now),
and many other applications. There's a
blueprint on Launchpad to get preload integrated into the default Ubuntu
install, and I think it would be great
if we tried to get this done. Right now, there's only one subscriber to
the blueprint, so I don't think it's been
noticed... but we can use our numbers to try to get it out there to
whoever matters.

If you want to see the speed increases I'm talking about, just do sudo
aptitude install preload to
install it. You won't see speed increases right away, but after a little
bit of use, it'll figure out what you use
most and preload it into memory before you load the application, so
cold-start time will be greatly improved.
