title: Perl Threads faster than Sequentially processing?
body: <p>Just wanted to ask whether it's true that parallel processing is faster than sequentially processing.
  I've always thought that parallel processing is faster, so therefore, I did an experiment.
  I benchmarked my scripts and found out that after doing a bunch of </p>
  
  <pre><code>sub add{
  
      for ($x=0; $x&lt;=200000; $x++){
          $data[$x] = $x/($x+2);
      }
  
  }
  </code></pre>
  
  <p>threading seems to be slower by about 0.5 CPU secs on average. Is this normal or is it really true that sequentially processing is faster?</p>
