1. How many lines in your file?
  2. Over what range are the keys and values spread?
  3. How many lookups per load?

    Eg. Is this a web app that does half a dozen lookups per load, or a system app that does thousands per load.

  4. Is concurrency a requirement?
  5. How often does the dataset change?
  6. How fast a lookup are you hoping for?
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.
"Too many [] have been sedated by an oppressive environment of political correctness and risk aversion."
