Thanks. I'll look into that module. I'm not having performance issues per se, but the code seems to parse ~15-20 songs per second, which is ~20 minutes for the 19k file in my mp3 library. Not terrible, but I have a feeling it can be faster. I don't notice an CPU or RAM hit while it's running, but I haven't looked closely.

    Just to compare speed: I have an MP3 library on network attached storage which I access through WiFi, so it is not terribly fast. It contains 5900 MP3-songs in 500 folders and is 35 GB large. Indexing it with MP3::Find and MP3::Find::DB (using an SQLite database) took 3022 seconds, so it is almost 2 seconds per song songs per second. I am sure if the songs are on a local harddisk, the speed would be higher. The processor never maxed-out, so the bottle-neck is most probably in the network and/or harddisk.

    Given these circumstances it seems therefore you have indeed some room to improve the speed of your script.

    Update: fixed typo.
