The page allocator may be getting significantly faster, but that is _not_ the only reason why we use partial slabs. Higher order slabs, such as the default for kmalloc-2048, kmalloc-4096, etc., increase the liklihood of having cpu slabs at that order as opposed to order fallback with a sufficiently long uptime.
