One cited insert test of 1000 records was 20 times faster (than the original SQLite with its B-Tree implementation). [58] LMDB is available as a backing store for other open source projects including Cyrus SASL, [59] Heimdal Kerberos, [60] and OpenDKIM. [61] It is also available in some other NoSQL projects like MemcacheDB [62] and Mapkeeper. [63]
