[erlang-questions] Dict performances

[Alain O'Dea]

It's unlikely to have changed much.  You'd need to cross-reference the
history of dict.erl:
https://github.com/erlang/otp/commits/dev/lib/stdlib/src/dict.erl

It hasn't changed since OTP was put on GitHub, but that was pretty
recent and it would interesting to see changes prior to that.

I suggest benchmarking your usage against ets and gb_trees. timer:tc
is good for this: http://www.erlang.org/doc/man/timer.html

A possibly awful example of using timer:tc for logarithmic benchmarking:
