BerkeleyDB is actually faster than CDB_File, as seen in previous benchmarks on PerlMonks. I wouldn't recommend using memcached for anything where lost data would be considered a problem.

    I only found SQLite vs CDB_File vs BerkeleyDB, and there CDB_File came out on top of BerkeleyDB where it entered the contest. On the other hand, that benchmark is from 2002, and CDB_File didn't make it into the second round due to build problems on Windows.

      In the followup by demerphq, he totally destroyed that benchmark just by switching BerkeleyDB to BTree.
