    Yeah, that number scared me too when I first saw it, as the time will make
    the script totally useless. Then after migrating to the RAM based database
    file, the database handling time could be cut down to 1 second.

    I guess the sqlite itself realize the shortcoming too, it also provide a
    native way to use in-memory database by specifying ":memory":
    con = sqlite3.connect(":memory:")

    Thanks,
    Feng
