Every program started on those systems must allocate a large contiguous block for the code and data, and every malloc >1 page is the same. If memory is too fragmented, starting new programs fails. The high-order page-allocator defragmentation lately should help with that. The different behaviours of SLAB/SLUB might result in different levels of fragmentation, so I wonder if anyone has compared them on MMU-less systems or fragmentation-sensitive workloads on general systems.
