It sounds like OS X fails to optimize repeated lookups of the same
symlink. I haven't tried to do any performance measurement of this
myself, but if true a gripe to Apple would be in order. Most of the
designs I've seen for clean tablespace handling will depend on symlinks
much more than we do today, so a performance penalty for symlinks will
*really* hurt further down the road.
