Hi,
I've uploaded a patch to optimize eager loading, which changes the
code to spend less time in ruby -
http://dev.rubyonrails.org/ticket/10011
The problem is because of following line in
associations.rb:#construct_associations :
collection.target.push(association) unless
collection.target.include?(association)
This basically compares every processed object with the new object, to
see if it hasn't been instansiated already.
For testing, I created two simple models :
class Person < ActiveRecord::Base
has_many :items
end
class Item < ActiveRecord::Base
belongs_to :person
end
Data : 1 Person and 1000 items belonging to that person.
Performance Script : http://pastie.caboo.se/111774

After the patch : http://m.onkey.org/after.html
Please test the patch if you can and also post your comments/suggestions.
