DBM Files are good for exact matches, but you aren't doing an exact match. You are doing a substring match. To do that efficiently (that is, significantly faster than matching all files) you either need a complicated datastructure (that you will have to make persistant somehow) or use lots and lots of (disk)memory. Or some combination of both. It would also mean that updating the information is going to take longer.
