re: A Little Story About the 'no' Command VIEW POST


Sorry if you know why this slow, calling IO.puts every times make performance wrong. system call block until finish of I/O. I'm not good at Elixir, but you've better to use buffer for writing. Actually, yes command does not call write(2) for each lines.


I didn't know that IO.puts takes such a cost. I'll try to use buffer with Elixir. Thanks for your advice!!
