Depends on the store - for example memcache won't store anything
larger than 1Mb
It might be preferable to store the objects that are slow to fetch
rather than the view itself, for example

@friends =3D Rails.cache.fetch("friends_for_#{session[:fbuser]
["credentials"]["token"]}") do
  graph =3D Koala::Facebook::GraphAPI.new(session[:fbuser]
["credentials"]["token"])
  graph.get_connections("me", "friends").to_a
end
