Hmph, it seems to be in the noise (I'm testing with an AMD system though). Some boots SLAB is faster, other boots, SLQB is. Could be a matter of luck in cacheline placement maybe?
I think this benchmark (after the slab rcu patch) will be pretty trivial for any slab allocator because it will basically be each CPU allocating then freeing an object.
