without_instanciation

https://rubygems.org/gems/without_instanciation
On large results of ActiveRecord queries, instanciation + GC of objects has a real cost of allocating memory, setting values, and after all GC garbage ... Inside a without_instanciation block, data is returned as hash of values. Objects instanciation process id skipped and though GC of theses objects too. Performance up to 80% for large query result. Of course, you no longer work with Ruby AR objects in this block.
