SLUB does not do things like managing object level NUMAness but relies on the page allocator to spread page size blocks out. It will only use one rotor and therefore not skip nodes. The SLAB issues are a result of the way object level NUMA awareness is implemented there. SLOB also does not do the SLAB thing and defers to the page allocator. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
