Hey guys, since current_user is a method used in every request I decided to give it a few benchmarks

I'm gisting this so if anyone may find good literature

here was my start point question:
which is best?
(yes this approach doesn't validate an auth token)

  def current_user
    if session[:user_id]

SELECT `sales`.* FROM `sales`
  INNER JOIN `properties` ON `properties`.`id` = `sales`.`property_id`
  WHERE (properties.zip = 33160)
  ORDER BY sale_date DESC
  LIMIT 10
