5% isn't much for sitting around for hours while gnome compiles. Currently its reinstalling itseld doing a bootstrap on my laptop. Its been doing that for over 4 hours now.

So can you get a real performance improvement? By real I mean noticeable?

I'll complete the installation and then try it for a week. My current impression is that its more trouble than its worth. But patience is not one of my virtues. Also its worth saying that anyone who considers the Debian installer to be rough should try Gentoo. Basically, you boot from a CD, create your partitions, chroot into the installtion directory and do everything from the command line. Not a dialog box to be seen. Still, mustn't grumble as its worked so far...
