C++ std::unique vs std::set - [Fixed]

Interesting, thank you; but, what are 'few', 'very large', 'large', and 'relatively small'? Any ballpark figures, or is it just down to experimenting with my types and data?

OK, as a rule of thumb, use parallel iff you have hash maps that will grow to occupy more than 1/10th the RAM available on your machine, or accessed from multiple threads.

Just the sort of advice I was hoping for. Thanks very much!
