### Use Puma as a web server
**Use Puma as a web server**
Heroku recommends to use Puma instead of the default web server to improve the responsiveness of your app on [a number of levels](http://blog.scoutapp.com/articles/2017/02/10/which-ruby-app-server-is-right-for-you).
Heroku recommends to use Puma instead of the default web server to improve the responsiveness of your app on [a number of levels](http://blog.scoutapp.com/articles/2017/02/10/which-ruby-app-server-is-right-for-you). First, add the gem in your _Gemfile\_custom_ file:
Since v1.0.0, CONSUL uses puma for the development and test environments. To use it in production as well, move the gem outside of the group `group :development, :test` in your _Gemfile_:
```
```ruby
gem 'puma'
```
Then you need to create a new file named _puma.rb_ \(your _config_ folder is a good place to store it\). Here is a standard content for this file:
```
workers Integer(ENV['WEB_CONCURRENCY'] || 1)
threads_count = Integer(ENV['RAILS_MAX_THREADS'] || 5)
threads threads_count, threads_count
preload_app!
rackup DefaultRackup

# Worker specific setup for Rails 4.1+
# See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
ActiveRecord::Base.establish_connection
end
If you want to allow more concurrency, uncomment the line:
```ruby
workers ENV.fetch("WEB_CONCURRENCY") { 2 }
```
You can find an explanation for each of these settings in the [Heroku tutorial](https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server).
The last part is to change the _web_ task to use Puma by changing it to this in your _heroku.yml_ file:
```
```yml
web: bundle exec puma -C config/puma.rb
```
### Add configuration variables to tune your app from the dashboard
The free and hobby versions of Heroku are barely enough to run an app like CONSUL. To optimise the response time and make sure the app doesn't run out of memory, you can [change the number of workers and threads](https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#workers) that Puma uses.
My recommended settings are one worker and three threads. You can set it by running these two commands:
```bash
heroku config:set WEB_CONCURRENCY=1
heroku config:set RAILS_MAX_THREADS=3
```
I also recommend to set the following:
```bash
heroku config:set RAILS_SERVE_STATIC_FILES=enabled
heroku config:set RAILS_ENV=production
```
