If speed meant NOTHING you'd do it by hand.

The point is that inserting into a flat file means rewriting the entire file each time, unless you store updates and do them in groups. Imagine, if your 2mb flat file grows by 4 bytes each iteration, you're moving around 2mb of data each time you try to add 4 bytes. That's a 2,000,000 bytes of data reading and rewriting for each 4 byte insertion. Speed has got to mean something.

I think your solution may be a good one. If building up the dataset is a one-time deal, do it in a database, and then transfer the completed product to a flat file where it can be read quickly.

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 How to display code and escape characters are good places to start.
