Based on your description, it sounds like there are significant gains to be made in efficiency and speed by rewriting. I'm interested in a follow-up -- can you give us some simple benchmarks when you are done, such as old size, new size, prior system calls, new system calls, and best of all, performance on a moderate data set?

Not only would such a magnanimous post generate cascading blankets of appreciative warmth from your fellow monks, the excercise might give you some impressive "bonus" information to pass along to the client in question, information that might make you stand out when they cast around for future contracts.

Uh, that of course assumes that the decision-maker at the client shop is not the original author of the script with a fragile ego to boot. ;-)

• 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.
