Does it make any sense to incorporate several approaches, and make the system adaptive?

Let's say we've done some benchmarking (which I haven't), and I have these systems, breakpoints and savings (negative is space saved):

string length system 0-10 plain (+10%) 11-50 7bit packing (-10%) 51-100 huffman (-20%) 101- LZ (-35%)
Now, the first 2 bits (or byte, if plain) indicates which system is being used. Note that the plain text system suffers because of the overhead of the leading indicator.

Would a system like this work? What would the breakpoints be? Is it worthwhile to combine any elements together?

Or is it the case that benchmarking should be used to find the system that gives the best performance on the typical data, and stick with that?

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).
