I thought the small files of the portage tree especially profit from the
notail option in reiserfs? Did you change the block size?

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.
