Hmmmm... I do not see a regression (up to date slub with all outstanding patches applied). This is without any options enabled (but antifrag patches are present so slub_max_order=4 slub_min_objects=16) Could you post a .config? Missing patches against 2.6.21-rc7-mm2 can be found at http://ftp.kernel.org/pub/linux/kernel/peopl/christoph/slub-patches
