Benchmark (2011), compares LevelDB (revision 39) against SQLite3 (version 3.7.6.3) and Kyoto Cabinet's (version 1.2.67) TreeDB (a B+Tree based key-value store):
http://leveldb.googlecode.com/svn/trunk/doc/benchmark.html

Benchmark (2012), compares LevelDB version 1.5 (git rev dd0d562b4d4fbd07db6a44f9e221f8d368fee8e4), SQLite3 (version 3.7.7.1) and Kyoto Cabinet's (version 1.2.76) TreeDB (a B+Tree based key-value store), Berkeley DB 5.3.21, and OpenLDAP MDB (git rev 2e677bcb995b63d36461eea254f2134ebfe29da2)

Bottom line: LevelDB is >= Sqlite3 (performance-wise)
