I'm using rails5.2. For testing i've created below controller.

class IndexController < ApplicationController
    def index        
        sleep(10)
        render text: "done"
    end
end

If I make 5 parallel requests, 1st request takes 10s, 2nd takes 20s, 3rd takes 30s and so on..

myAppRails5 aravind$ bin/rails server
=> Booting Puma
=> Rails 5.2.0 application starting in development 
=> Run `rails server -h` for more startup options
Puma starting in single mode...
* Version 3.11.4 (ruby 2.5.1-p57), codename: Love Song
* Min threads: 5, max threads: 5
* Environment: development
* Listening on tcp://0.0.0.0:3000
Use Ctrl-C to stop

Puma configuration : Min threads: 5, max threads: 5 Rails 5.2.0 application starting in development

development.rb

puma.rb

As per puma doc, threaded is supported. How do I achieve multi threading here?

Take a look at [this](https://stackoverflow.com/a/30228125/4160532), check if you have made all the necessary configuration changes. – Kedarnag Mukanahallipatna Sep 21 '18 at 06:50

You should post the the full log of when the server is starting, from Booting Puma to the list of workers. Also, try calling lsof -i :3000 to check how many processes are started – Uelb Sep 21 '18 at 07:40
@Oxynum - Updated question for full log. lsof response which making multiple calls at https://justpaste.it/6r7ma – Hideandseek Sep 21 '18 at 09:12
What operating system are you using? I'm not seeing this behavior on OS X 10.13.6 with puma. – Mike Gorski Sep 21 '18 at 17:18
