Question

Many people experienced issues with memory usage when switching their Rails app from Ruby 2.0 to Ruby 2.1 on Heroku. For example, see Memory usage increase with Ruby 2.1 ver

Answer 1

I gave Ruby 2.2 a try with Rails 4.2 and the same memory problems that plagued Ruby 2.1 also occurred. I am switching back to Ruby 2.0. Rails 5 will require Ruby 2.2 and higher so I hope someone will find a way to fix this.
