Dear Monks

I have a new problem, which is challenging of course, but when implementing the solution it would be nice to know that I've chosen the correct one!
The tool I'm writing has to tell, out of many objects (all instances from the same package), which objects are duplicates. In a loop I can compare the data from 2 objects at the time and determine which objects I have to remove. However this will be too slow, those objects contain a lot of ASCII data! (performance is very important).

The best solution (I think) would be to create a fingerprint once per object which is used in the comparison!
But what is the fastest way to make fingerprints, MD5 ?

Thnx
LuCa

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