Just tell us what the input looks like, how you want it processed and stored in the database. I think that would be faster than wading through 162 lines of code containing if/else if statements that go four layers deep in places.

I can suggest that there is often room for improvement in working with the database by preparing statements once, and executing multiple times, rather than doing $dbh->do(...). Also, in the case of SQLite at least, transactions that span multiple inserts or updates will often mitigate the problem of being IO bound, since the transactions are often held in memory until they're committed. Re: Challenge: 8 Letters, Most Words demonstrates this technique.
