This is our current Travis configuration for our standard Rails 4 + Ruby 2 projects that have Capybara Webkit test suites and Postgres databases. It relies on the bundle_cache.rb and bundle_install.sh files from http://randomerrata.com/post/45827813818/travis-s3 to cache gem bundles for much faster test suite setup time.

Job queues in Ruby and Postgres

A few lines of Ruby with pg driver is a simple alternative to a job queuing library. Job queues are defined as database tables and workers are defined in one Ruby file.

queuea: bundle exec ruby queue/a.rb
queueb: bundle exec ruby queue/b.rb

Common performance symptoms

The two most common performance symptoms are with throughput or timeouts.

An application's maximum throughput can be measured by how many requests per second it serves; New Relic reports this number as "rpm," which means "requests per minute." Throughput will be limited by how long the average request takes to process and how may servers are available to handle processes. Heroku calls these servers "dynos."
