Your title and question suggested to me a need for appropriate table indexing to improve database performance. But your code shows only a single INSERT on an unindexed table. An index slows down table INSERTs (but is often justifiable because of the needs of future queries on the data set). It is also faster than DROPping and rebuilding those indexes every time you do an INSERT, except for bulk INSERTs when that strategy can make sense.

If you are having some performance issues with this code, I doubt it is in the database interactions.

I'd suggest using Devel::NYTProf to start to get a handle on where the resources are being used. I'd guess that parsing your mp3 library is not a trivial task.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
