You may also consider using forks. Modern OSses give the appearance all the data is copied, but they'll implement it using COW, so it reality, data is only copied when it's rewritten in a process.

Of course, as pointed out elsewhere in the thread, first creating threads (or processes) and only then reading in the data wins.

Title:
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.
