I can't imagine it's the reading of the small files of that's slowing it
down, otherwise ReiserFS would have a bad reputation. So is it the
writing, or something in cp's directory walking? Have you tried tar'ing up
the osurce directyory and see it is quick? Then untar the tar ball? That
would point to it being the read or the write thats slow. If both go fast
then it's obvious a cp problem.
