I'd be tempted to load all the data into a hash, then use a tie interface that computes what the closest preceding data point would be and returns the value corresponding to it.

As with most questions of this sort, the proof is in the benchmarking, and if you really want to optimize for search speed, you'll want to benchmark.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
