Actually there is. Most MUMPS implementations are multi-way B-trees. Real true B-trees suffer badly in real-life, nearly every action is a pointer split. The performance of MUMPS sparse arrays is in the shared buffer pools and broad pointer structures that get you to any data location in a 1,000,000 element database in 7 physical disk accesses or less.
