Both on Memory usage tracking and precise data on load/input.
Regarding scale, we are aware of the issue, listed in limitations: https://github.com/memgraph/memgraph/tree/master/tests/mgben.... Next versions will probably have a billion nodes/relationships.
Actually, Neo4j is particularly slow on writes, import/load times were 50x faster on Memgraph, but we didn't show it. Will do it in the next version for all vendors.
