Memory bloat in Ruby happens when someone loads a lot of data to the memory. Ruby Virtual Machine does not return most of the allocated memory to the operating system even after data is collected as a garbage. It’s not a big deal for local development or console programs, but if you have a bloat in the big Rails app it might cost you a lot of money.

It is quite easy to find a fix memory bloat when it happens, but can we prevent it?
