Yes there's some overhead for DBI connections, but unless your program can access particular files by name (that is, your program is given a specific file to access without having to do any searching) then MySQL is going to definitely be faster. For example, if you have one file per user, and each file is named after the user, and the only thing your program will ever do for User X is access File X, then flat files will be quicker.

On the other hand, if there are multiple files per user, or you want to slice and dice the data in different ways (i.e. "Give me all the files for User X, created between January and March, that have to do with 'Foo'") then you should just go ahead and do the relational database tango and use MySQL. Although it's true that MySQL builds its internal data structures on top of whatever file system it's in, it gets HUGE speed advantages over flatfiles from the proper use of indexes, allowing you to get to just the data you need without having to search through every file in the database.

Think about what you're doing (and what you're likely to want to do with your program in the future) and make the appropriate decision. :-)

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
