I thought the small files of the portage tree especially profit from the notail option in reiserfs?

Would the journaling overhead be noticeable? I also had used ext2 for my portage tree first, then I read somewhere that reiserfs would be the best. BTW, I have distfiles and pkgdir somewhere else, if not the fsck would not be so fast. Just for fun, I just copied my $PORTDIR into my tmpfs, emerge -DpN @system @world takes between 81 and 53 seconds. With reiserfs, I get 130 seconds first ($PORTDIR was unmounted first and mounted again to clear the caches), and 57 seconds in the second attempt. I had expected that tmpfs would be even faster. I think I just keep it the way it is now. Wonko
