You understand correctly. My point was LMDB does not have checkpoints/compaction steps where it "silently" in the background copies data around. When writes are large, this is an important point. LevelDB/RocksDB type stores work great for small values, but perform very poorly for large writes because they copy data around in compaction steps.
