Benchmark different ways to construct a binary in Elixir
Under the project directory, execute:
mix run run.exFrom my personal computer, the result is
Erlang/OTP 18 [erts-7.3] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]
Elixir 1.3.1

Comparison:
list_loop_with_list_to_binary_test 133.56 K
list_loop_with_iodata_to_binary_test 132.40 K - 1.01x slower
binary_loop_test 110.02 K - 1.21x slower
list_comprehension_test 106.60 K - 1.25x slower
list_iter_test 99.28 K - 1.35x slower
binary_comprehension_test 98.06 K - 1.36x slower
The best solution would be list_loop_with_list_to_binary_test
