Hence the existence of forks.pm. It has the improved efficiency of creating a new "thread" because it uses fork() to do that
  1. How long does it take to start one thread per core? Answer: 0.0334138870239258 / 4.

    Sure, fork will be faster. But on any process long-running enough to be worth multi-threading, 0.01 per core is but a drop in the ocean.

  2. How long does it take to communicate 1000 work items to each of those work threads? Answer: 4 cores; 4 threads; 4000 items; 0.113806962966919 seconds.

    How long will it take to

    1. freeze those work items;
    2. send them via sockets;
    3. receive them at the other end;
    4. unfreeze them?

    And I bet that establishing those socket connections more than negates the lower start-up cost of fork.

Which timing is the more important?
