I also don't know why there is the difference in benchmarks. After converting to Perl 5.10 code for my machine (push $aref.. and keys @array aren't valid until 5.14), I got similar results.

If you are using a real disk drive and database is not "online", then
    $dbh->do('PRAGMA synchronous = 0');
sped your 'old' benchmark up from 47 secs to 32 secs on my older model machine. The SQLite app that I'm working on now takes in this range for a 300K row table with mainly varchar's to be created. So I think you are in the "zone of reason" in terms of performance. Since you are mainly using ints, might be interesting to try with numeric values instead of text in your benchmark.

There is a bulk import facility for SQLite that works with a csv format. I have never used it but, it might be quicker. I don't know where your actual data comes from.
