It would almost certainly be considerably quicker to query the names from the DB in bulk and build a hash in perl. And then just process your file against the hash.

A 10 million key hash should take 1.5 GB. And looking up 2 million keys against a 10 million key hash takes around 5 seconds.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
