The looseness of coupling versus performance is one of the most common, and often the most difficult decisions I make in my job as a programmer.

I *love* modular designs - they feel right for me. I like it when I can reuse a module - so much time saved ! I like thinking modularly, it simplifies the process and allows to build complex programs easily.

However, modularity often comes at the price of degraded performance. It's a basic fact of life, tighter coupling improves performance because of lessening the cost in the interfaces.

The best solution to this problem, IMHO, is the common engineering trade-off. I tend to design modularly, then profile. Wherever the performance matters most (remember those 80/20 rules) I tighten the coupling.

Title:
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.
