I think you need to clarify the operating environment and operational requirements of your question.

  1. Is this 3 long running concurrent processes? Or with one or more transient (web-server-like) processes?
  2. Is that a single 40-byte string? Or one 40-byte string per id? (If so, how many ids?)
  3. You mention persistence. Is that persistence between connections? Or persistence across server outages?
  4. Are the other two processes also Perl? Or C? Other?
  5. Do all three need read-write access? Do you need coherency?
  6. Many other questions that would be answered or avoided by a much clearer description of the actual purpose.
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
