Excellent!

One question. Why   $dbh->do('PRAGMA default_synchronous = off'); in the default (commit after each insert) case? Is this not something that could be hidden beneath the options on the connect?

    Otherwise SQLite does a fflush on every row, making it much slower ;-)

    The option is only relevant if you're worried about data integrity during a filesystem crash.

      Uh... That sounds like you're defeating AutoCommit => 1, which would make this a misleading benchmark.

        Not at all. None of the others were doing fflush per row, so why should SQLite suffer?
